| |  |  | we, us, our, the Company and Enersis Chile refer to Enersis Chile S.A. and our combined entities;
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | Enersis Américas refers to Enersis S.A. prior to the demerger of Enersis Chile and to Enersis Américas S.A. (formerly named Enersis S.A.), which continues to hold the non-Chilean businesses
and assets of Enersis S.A. after the demerger of Enersis Chile;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Endesa Chile refers to Empresa Nacional de Electricidad S.A., both before and after the separation, subsequent to which it holds only Chilean assets; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Chilectra Chile refers to Chilectra S.A. prior to the demerger of Chilectra Américas S.A. and Chilectra S.A., which continues to hold the Chilean businesses and assets of the pre-demerger Chilectra
S.A. after the demerger of Chilectra Américas S.A.

We are a Chilean company engaged in the electricity
generation and distribution businesses in Chile through our combined entities and jointly-controlled entities. As of the date of this Report, we own 60.0% of Empresa Nacional de Electricidad S.A. (Endesa Chile), a Chilean
electricity generation company holding electricity generation operations in Chile, and 99.1% of Chilectra S.A. (Chilectra Chile), a Chilean electricity distribution company with operation in the Santiago Metropolitan Area. As of the
date of this Report, Enel beneficially owns 60.6% of us through its wholly-owned subsidiaries.

Overview of the Reorganization

Enersis Américas and other companies that are ultimately controlled by Enel are in the process of reorganizing its corporate structure
to separate the electricity generation and distribution businesses and assets of Enersis and its combined entities in Chile from the generation, transmission and distribution businesses in Argentina, Brazil, Colombia and Peru (the
Reorganization).

The Spin-Offs

On April 2016, each of Endesa Chile and Chilectra Chile spun-off to their respective shareholders pro rata the shares of two new Chilean
entities Endesa Américas S.A. (Endesa Américas) and Chilectra Américas S.A. (Chilectra Américas), that holds the non-Chilean businesses, comprised exclusively of their respective ownership
interests in shares of companies domiciled outside of Chile, formerly held by Endesa Chile and Chilectra Chile, respectively (the Endesa/Chilectra Spin-Offs). Each of the Endesa/Chilectra Spin-Offs was effected by means of a procedure
under Chilean corporate law called a división or demerger. Endesa Chile continues to hold the Chilean businesses and assets of Endesa Chile and Chilectra Chile continues to hold the Chilean businesses and assets
of Chilectra Chile.

Enersis Américas, as the former owner of 60.0% of Endesa Chile and the 99.1% of Chilectra Chile, currently
owns 60.0% of Endesa Américas and 99.1% of Chilectra Américas as a result of the Endesa/Chilectra Spin-Offs and the minority shareholders of Endesa Chile and Chilectra Chile own their respective percentage interests in Endesa
Américas and Chilectra Américas, respectively, based on a pro rata distribution of the spin-off company shares. The shares of Endesa Américas and Chilectra Américas are listed and traded on the Chilean Stock Exchanges and
the American Depositary Receipts (ADRs) of Endesa Américas are listed and traded on the New York Stock Exchange (NYSE).

Enersis S.A. conducted a demerger to separate into two companies: Enersis Chile S.A. and Enersis Américas S.A. The new
company, Enersis Chile S.A. (Enersis Chile) was established as a separate company and was assigned the equity interests, assets and associated liabilities of Enersis S.A.s businesses in Chile, including the equity interests in each
of Endesa Chile and Chilectra Chile after giving effects to the demergers of Endesa Chile and Chilectra Chile on March 1, 2016 (the Separation). As a result of the Separation, the equity interests, assets and associated liabilities
of the non-Chilean businesses of Enersis S.A., including the equity interests in Endesa Américas and Chilectra Américas are continued to be held by Enersis Américas. Enersis S.A. also changed its name to Enersis Américas
S.A. Upon the completion of the Separation, Enersis Chile registered its shares with the Securities Registry of the SVS under Chilean law and the SEC under applicable U.S. federal securities laws. On April 21, 2016, Enersis Américas
distributed to its shareholders shares of Enersis Chile in proportion to their share ownership in Enersis Américas based on a ratio of one share of Enersis Chile for each outstanding share of Enersis Américas (the
Distribution, and together with the Separation, the Spin-Off).

Enel beneficially owns 60.6% of Enersis Chile as a
result of the Spin-Off, and the minority shareholders of Enersis Américas own their respective percentage interest in Enersis Chile. The shares of Enersis Chile are listed and traded on the Chilean Stock Exchanges and the ADRs of Enersis
Chile are listed and traded on the NYSE. The following chart sets forth our corporate structure as of the date of this report:

PRESENTATION OF INFORMATION

Financial Information

In this Report, unless otherwise specified, references to U.S. dollars or US$, are to dollars of the United States of
America; references to pesos or Ch$ are to Chilean pesos, the legal currency of Chile; references to  or Euros are to the legal currency of the European Union; and references to UF
are to Development Units (Unidades de Fomento).

The UF is a Chilean inflation-indexed, peso-denominated monetary unit that is
adjusted daily to reflect changes in the official Consumer Price Index (CPI) of the Chilean National Institute of Statistics (Instituto Nacional de Estadísticasor INE). The UF is adjusted in monthly
cycles. Each day in the period beginning on the tenth day of the current month through the ninth day of the succeeding month, the nominal peso value of the UF is indexed in order to reflect a proportionate amount of the change in the Chilean CPI
during the prior calendar month. As of December 31, 2015, one UF was equivalent to Ch$ 25,629.09. The U.S. dollar equivalent of one UF was US$ 36.09 as of December 31, 2015, using the Observed Exchange Rate reported by the
Central Bank of Chile (Banco Central de Chile) as of December 31, 2015 of Ch$ 710.16 per US$ 1.00. The U.S. dollar observed exchange rate (dólar observado) (the Observed Exchange Rate), which
is reported by the Central Bank of Chile and published daily on its webpage, is the weighted average exchange rate of the previous business days transactions in the Formal Exchange Market

The Central Bank of Chile may intervene by buying or selling foreign currency on the Formal Exchange Market to maintain the Observed Exchange
Rate within a desired range.

As of March 31, 2016, one UF was equivalent to Ch$ 25,812.05. The U.S. dollar equivalent of one UF
was US$ 38.54 on March 31, 2016, using the Observed Exchange Rate reported by the Central Bank of Chile as of such date of Ch$ 669.80 per US$ 1.00.

Our combined financial statements and, unless otherwise indicated, other financial information concerning us included in this Report are
presented in Chilean pesos. We have prepared our combined financial statements in accordance with International Financial Reporting Standards (IFRS), as issued by the International Accounting Standards Board (IASB).

All of our combined entities are integrated and all their assets, liabilities, income, expenses and cash flows are included in the combined
financial statements after making the adjustments and eliminations related to intra-group transactions. References in this Report to combined entities refer to entities that are controlled, either directly or indirectly, by Enersis Chile. Control is
achieved when Enersis Chile (i) has power over the entity, (ii) is exposed, or has rights, to variable returns from its involvement with the entity and (iii) has the ability to use its power to effect its returns. Enersis Chile has
power over its combined entities when it holds the majority of the substantive voting rights or, when it has less than a majority of the voting rights, and those rights are sufficient to give it the practical ability to direct the relevant
activities of the entity unilaterally.

For the convenience of the reader, this Report contains translations of certain Chilean peso
amounts into U.S. dollars at specified rates. Unless otherwise indicated, the U.S. dollar equivalent for information in Chilean pesos is based on the Observed Exchange Rate for December 31, 2015, as defined in Item 3. Key
Information  A. Selected Financial Data  Exchange Rates. The Federal Reserve Bank of New York does not report a noon buying rate for Chilean pesos. No representation is made that the Chilean peso or U.S. dollar amounts shown
in this Report could have been or could be converted into U.S. dollars or Chilean pesos, as the case may be, at such rate or at any other rate. See Item 3. Key Information  A. Selected Financial Data  Exchange
Rates.

##### Table of Contents

Energy losses experienced by generation companies during transmission are calculated by
subtracting the number of GWh of energy sold from the number of GWh of energy generated (excluding their own energy consumption and losses on the part of the power plant), within a given period. Losses are expressed as a percentage of total energy
generated.

Energy losses during distribution are calculated as the difference between total energy purchased (GWh of electricity demand,
including own generation) and the energy sold (also measured in GWh), within a given period. Distribution losses are expressed as a percentage of total energy purchased. Losses in distribution arise from illegally tapped energy as well as technical
losses.

Calculation of Economic Interest

References are made in this Report to the economic interest of Enersis Chile in its related companies. In circumstances where we
do not directly own an interest in a related company, our economic interest in such ultimate related company is calculated by multiplying the percentage of economic interest in a directly held related company by the percentage of economic interest
of any entity in the ownership chain of such related company. For example, if we own 60% of a directly held combined entity and that combined entity owns 40% of an associate, our economic interest in such associate would be 60% times 40%, or 24%.

Rounding

Certain
figures included in our combined financial statements have been rounded for ease of presentation. Percentages expressed in this Report may not have been calculated using rounded figures, but by using amounts prior to rounding. For this reason,
percentages expressed in this Report may vary from those obtained by performing the same calculations using figures in our combined financial statements. Certain other amounts that appear in the tables in this Report may not total exactly due to
rounding.

Exchange Rates

Fluctuations in the exchange rate between the Chilean peso and the U.S. dollar will affect the U.S. dollar equivalent of the peso
price of our shares of common stock on the Santiago Stock Exchange (Bolsa de Comercio de Santiago), the Chilean Electronic Stock Exchange (Bolsa Electrónica de Chile) and the Valparaíso Stock Exchange (Bolsa de
Corredores de Valparaíso). These exchange rate fluctuations affect the price of our American Depositary Shares (ADSs) and the conversion of cash dividends relating to the common shares represented by ADSs from Chilean pesos to
U.S. dollars. In addition, to the extent that significant financial liabilities of the Company are denominated in foreign currencies, exchange rate fluctuations may have a significant impact on earnings.

In Chile, there are two currency markets, the Formal Exchange Market (Mercado Cambiario Formal) and the Informal Exchange Market
(Mercado Cambiario Informal). The Formal Exchange Market is comprised of banks and other entities authorized by the Central Bank of Chile. The Informal Exchange Market is comprised of entities that are not expressly authorized to operate in
the Formal Exchange Market, such as certain foreign exchange houses and travel agencies, among others. The Central Bank of Chile has the authority to require that certain purchases and sales of foreign currencies be carried out on the Formal
Exchange Market. Both the Formal and Informal Exchange Markets are driven by free market forces. Current regulations require that the Central Bank of Chile be informed of certain transactions that must be carried out through the Formal Exchange
Market.

The U.S. dollar Observed Exchange Rate, which is reported by the Central Bank of Chile and published daily on its web page,
is the weighted average exchange rate of the previous business days transactions in the Formal Exchange Market. Nevertheless, the Central Bank of Chile may intervene by buying or selling foreign currency on the Formal Exchange Market to
attempt to maintain the Observed Exchange Rate within a desired range.

The Informal Exchange Market reflects transactions carried out at
an informal exchange rate (the Informal Exchange Rate). There are no limits imposed on the extent to which the rate of exchange in the Informal Exchange Market can fluctuate above or below the Observed Exchange Rate. Foreign currency for
payments and distributions with respect to the ADSs may be purchased either in the Formal or the Informal Exchange Market, but such payments and distributions must be remitted through the Formal Exchange Market.

The Federal Reserve Bank of New York does not report a noon buying rate for Chilean pesos. As of December 31, 2015, the U.S. dollar
Observed Exchange Rate was Ch$ 710.16 per US$ 1.00.

As of
April 28, 2016, the U.S. dollar Observed Exchange Rate was Ch$ 663.40 per US$ 1.00.

Calculation of the
appreciation or devaluation of the Chilean peso against the U.S. dollar in any given period is made by determining the percent change between the reciprocals of the Chilean peso equivalent of US$ 1.00 at the end of the preceding period and
the end of the period for which the calculation is being made. For example, to calculate the devaluation of the year-end Chilean peso in 2015, one determines the percent change between the reciprocal of Ch$ 606.75, the value of one
U.S. dollar as of December 31, 2014, or 0.001648, and the reciprocal of Ch$ 710.16, the value of one U.S. dollar as of December 31, 2015, or 0.001408. In this example, the percentage change between the two periods is
negative 14.6%, which represents the 2015 year-end devaluation of the Chilean peso against the 2014 year-end U.S. dollar. A positive percentage change means that the Chilean peso appreciated against the U.S. dollar, while a
negative percentage change means that the Chilean peso devaluated against the U.S. dollar.

The following table sets forth the
period-end rates for U.S. dollars for the years ended December 31, 2011 through December 31, 2015, based on information published by the Central Bank of Chile.

A financial or other crisis in any region
worldwide can have a significant impact in Chile, and consequently, may adversely affect our operations as well as our liquidity.

Chile is vulnerable to external shocks, including financial and political events, which could cause significant economic difficulties and
affect its growth. If the Chilean economy experiences lower than expected economic growth or a recession, it is likely that our customers will demand less electricity and that some of our customers may experience difficulties paying their electric
bills, possibly increasing our uncollectible accounts. Any of these situations could adversely affect our results of operations and financial condition.

Financial and political crises in other parts of the world could also adversely affect our business. For example, instability in the Middle
East or in other oil producing regions could result in higher fuel prices worldwide, which in turn could increase the cost of fuel for our thermal generation plants and adversely affect our results of operations and financial condition.

In addition, an international financial crisis and its disruptive effects on the financial industry could adversely impact our ability to
obtain new bank financings on the same historical terms and conditions. A financial crisis could also diminish our ability to access the Chilean and international capital markets or increase the interest rates available to us. Reduced liquidity
could, in turn, adversely affect our capital expenditures, our long-term investments and acquisitions, our growth prospects and our dividend payout policy.

Chilean economic fluctuations as well as certain economic interventionist measures by governmental authorities may affect our results of
operations and financial condition as well as the value of our securities.

All of our operations are located in Chile.
Accordingly, our combined revenues may be affected by the performance of the Chilean economy. If local, regional or worldwide economic trends adversely affect the Chilean economy, our financial condition and results from operations could be
adversely affected. Moreover, insufficient cash flows for our combined entities could result in their inability to meet debt obligations and the need to seek waivers to comply with restrictive debt covenants.

During 2015, the Chilean economy was affected by (i) the economic uncertainty derived from the global contraction in several commodities
markets, such as copper, which has affected the exchange rate evolution and caused the Chilean peso to further depreciate, (ii) several law reforms still under discussion by the Chilean authorities (labor, education, among others), and
(iii) the possibility of a reform to the Chilean Constitution.

The Chilean government has exercised in the past, and continues to
exercise, a substantial influence over many aspects of the private sector, which may result in changes to economic or other policies. For example, in September 2014, the Chilean government approved the progressive increase of the corporate income
tax and a change in the tax system, which may have an additional negative effect upon non-Chilean holders of shares or ADSs. On February 8, 2016, Law 20,899 was enacted, which made adjustments to this tax reform. For further details regarding
Chilean tax considerations, please refer to Item 10. Additional Information  E. Taxation. Other governmental actions could involve wage, price and tariff rate controls and other interventionist measures, such as expropriation or
nationalization.

Future adverse developments in Chile or changes in policies regarding tariffs, exchange controls, regulations and
taxation may impair our ability to execute our strategic plans, which could adversely affect our results of operations and financial condition. Inflation, devaluation, social instability and other political, economic or diplomatic developments,
including the response by governments in the region to these circumstances, could also reduce our profitability. In addition, Chilean financial and securities markets are influenced by economic and market conditions in other countries and may be
adversely affected by events in other countries, which could adversely affect the value of our securities.

Our electricity business is subject to risks arising from natural disasters, catastrophic
accidents and acts of terrorism, which could adversely affect our operations, earnings and cash flow.

Our primary facilities
include power plants and distribution assets, pipelines, liquefied natural gas (LNG) terminals and re-gasification plants, storage and chartered LNG tankers. Our facilities may be damaged by earthquakes, flooding, fires, and other
catastrophic disasters arising from natural or accidental human causes, as well as acts of terrorism. A catastrophic event could cause disruptions in our business, significant decreases in revenues due to lower demand or significant additional costs
to us not covered by our business interruption insurance. There may be lags between a major accident or catastrophic event and the final reimbursement from our insurance policies, which typically carry a deductible and are subject to per event
policy maximums.

As an example, on February 27, 2010, Chile experienced a major earthquake in the Bío-Bío region, with
a magnitude of 8.8 on the Richter scale, followed by a very destructive tsunami. Our Bocamina I and Bocamina II thermal generation units, which are located near the epicenter, sustained significant damage as a result of the earthquake. More
recently, on September 16, 2015, Chile experienced an 8.3-magnitude earthquake in the Coquimbo region, followed by a tsunami, though there was no significant damage to any of our power facilities. In the distribution business, on May 6,
2015 a fire affected and damaged the Alonso de Córdoba Substation in Santiago, cutting power to 50,000 customers in eastern Santiago, where a significant part of the commercial and financial activity of the city is located. The short circuit
resulted in a massive power failure. Damages totaled US$ 5.8 million. The Chilean authority also fined Chilectra due to this event by 6,000 Monthly Tax Units (Unidades Tributarias mensualesor UTM; approximately Ch$
270 million using the UTM as of December 31, 2015.

We are subject to financing risks, such as those associated with
funding our new projects and capital expenditures, and risks related to refinancing our maturing debt; we are also subject to debt covenant compliance, all of which could adversely affect our liquidity.

As of December 31, 2015, our combined debt totaled Ch$ 845 billion.

Our debt had the following maturity profile:



| |  |  | Ch$ 18 billion in 2016;
| | - |  | -----------------------



| |  |  | Ch$ 16 billion from 2017 to 2018;
| | - |  | ---------------------------------



| |  |  | Ch$ 15 billion from 2019 to 2020; and
| | - |  | -------------------------------------



| |  |  | Ch$ 796 billion thereafter.
| | - |  | ---------------------------

Some of our debt agreements are subject to (1) financial
covenants, (2) affirmative and negative covenants, (3) events of default and (4) mandatory prepayments for contractual breaches, among other provisions. A significant portion of our combined entities financial indebtedness is
subject to cross default provisions, which have varying definitions, criteria, materiality thresholds and applicability with respect to combined entities that could give rise to such a cross default.

In the event that our combined entities breach any of these material contractual provisions, our creditors and bondholders may demand
immediate repayment, and a significant portion of our combined entities indebtedness could become due and payable. We may be unable to refinance our indebtedness or obtain such refinancing on terms acceptable to us. In the absence of such
refinancing, we could be forced to dispose of assets in order to make the payments due on our combined entities indebtedness under circumstances that might not be favorable to obtaining the best price for such assets. Furthermore, we may be
unable to sell our assets quickly enough, or at sufficiently high prices, to enable us to make such payments.

We may also be unable to
raise the necessary funds required to finish our projects under development or under construction. Market conditions prevailing at the moment we require these funds or other unforeseen project costs can compromise our ability to finance these
projects and expenditures.

Our inability to finance new projects or capital expenditures or to refinance our existing debt could
adversely affect our results of operation and financial condition.

We may be unable to enter into suitable investments, alliances and acquisitions.

On an ongoing basis, we review acquisition prospects that may increase our market coverage or supplement our existing businesses,
though there can be no assurance that we will be able to identify and consummate suitable acquisition transactions in the future. The acquisition and integration of independent companies that we do not control is generally a complex, costly and
time-consuming process and requires significant efforts and expenditures. If we consummate an acquisition, it could result in the incurrence of substantial debt and assumption of unknown liabilities, the potential loss of key employees, amortization
expenses related to tangible assets and the diversion of managements attention from other business concerns. In addition, any delays or difficulties encountered in connection with acquisitions and the integration of multiple operations could
have a material adverse effect on our business, financial condition or results of operations.

Because our generation business
depends heavily on hydrological conditions, droughts and climate change may adversely affect our operations and profitability.

Approximately 55% of our combined installed generation capacity in 2015 was hydroelectric. Accordingly, extreme hydrological conditions and
climate change could adversely affect our business, results of operations and financial condition. In the last few years, our results were affected due to the fact that hydrological conditions in Chile have been below the historical average.

In addition, the below-average hydrological conditions not only reduced our ability to operate our hydroelectric plants at full capacity, but
also resulted in increased water transportation costs for the operation of the San Isidro thermal power plant for cooling purposes. While Endesa Chile has entered into certain agreements with the Chilean government and local farmers regarding the
use of water for hydroelectric generation purposes, especially during periods of low water levels, if drought conditions persist or become worse, we may face increased pressure by the Chilean government or other third parties to further restrict our
water use (for further details regarding water agreements, please refer to Item 4. Information on the CompanyB. Business OverviewOperations Water Agreements). Droughts also affect the operation of our thermal plants,
including our facilities that use natural gas, fuel oil or coal as fuel, in the following manner:



| |  |  | During drought periods, thermal plants are used more frequently. Thermal plant operating costs can be considerably higher than those of hydroelectric plants. Our operating expenses could increase during these periods.
In addition depending on our commercial obligations, we may need to buy electricity at spot prices in order to comply with our contractual supply obligations and the cost of these electricity purchases may exceed our contracted electricity sale
prices, thus potentially producing losses from those contracts. For further information with respect to the effect of hydrology on our business and financial results, please refer to Item 5. Operating and Financial Review and Prospects
A. Operating Results1. Discussion of Main Factors Affecting Operating Results and Financial Conditiona. Generation Business.

| |  |  | Our thermal plants require water for cooling and droughts not only reduce the availability of water, but also increase the concentration of chemicals, such as sulfates in the water. The high concentration of chemicals
in the water we use for cooling increases the risk of damaging the equipment at our thermal plants as well as the risk of violating environmental regulations. As a result, we have had to purchase water from agricultural areas that are also
experiencing shortages of water. These water purchases may increase our operating costs and also require us to further negotiate with the local communities.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Thermal power plants burning natural gas generate emissions such as sulfur dioxide (SO2) and nitrogen oxide (NO) gases. When operating with diesel, they also
release particulate matter into the atmosphere. Coal fired plants generate emissions of SO2 and NO. Therefore, greater use of thermal plants during periods of drought increases the risk of
producing a higher level of pollutants.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In addition, according to certain weather forecast models, the drought that is
affecting the regions where most of our hydroelectric plants are located may last for an extended period and may recur in the future. A prolonged drought may exacerbate the risks described above and have a further adverse effect upon our business,
results of operations and financial condition.

Governmental regulations may adversely affect our business.

We are subject to extensive regulation on the tariffs we charge to our customers and on other aspects of our business, and these regulations
may adversely affect our profitability. For example, the Chilean government can impose electricity rationing during droughts or prolonged failures of power facilities. During rationing, if we are unable to generate enough electricity to comply with
our contractual obligations, we may be forced to buy electricity at the spot price, as even a severe drought does not release us from our contractual obligations as a force majeure event. The spot price may be significantly higher than our
costs to generate the electricity and can be as high as the cost of failure set by the Chilean National Energy Commission (Comisión Nacional de Energíaor CNE). This cost of failure, which is
updated semiannually by the CNE, is a measurement of how much final users would pay for one extra MWh under rationing conditions. If we are unable to buy enough electricity at the spot price to comply with our contractual obligations, we would have
to compensate our regulated customers for the electricity we failed to provide at the rationed price. Rationing periods have occurred in the past and may occur in the future. Our generation combined entities may be required to pay regulatory
penalties if they fail to provide adequate service under their contractual obligations. Material rationing policies imposed by Chilean regulatory authorities could adversely affect our business, results of operations and financial condition.

The Chilean governmental authorities may also delay the distribution tariff review process, or tariff adjustments may be insufficient to pass
through our costs. Similarly, electricity regulations issued by governmental authorities in Chile may affect the ability of our generation companies to collect revenues sufficient to offset their operating costs.

The inability of any company in our combined group to collect revenues sufficient to cover operating costs may affect the ability of that
company to operate as a going concern and may otherwise have an adverse effect on our business, financial results and operations.

In
addition, changes in the regulatory framework are often submitted to the legislators and administrative authorities and, some of these changes could have a material adverse impact on our business and affect our results. For instance, in 2005
there was a change in the water rights law in Chile that requires us to pay for unused water rights. In addition, the Chilean government is initiating a review of the current energy policies through an energy agenda presented in May 2014
and complemented in December 2015. This strategy aims to improve electricity service for the impoverished, to have 70% of national generation electricity from NCRE and to have 100% of new construction with energy control systems and smart energy
management by 2050. However external factors, primarily commodity prices, lower local energy prices and restrictions in the transmission system, have hindered the development of NCRE projects and some unrelated companies have disposed contracts that
were awarded in the last two distribution companies tenders. Meanwhile, Celta recorded an impairment loss of Ch$ 2.5 billion as of December 31, 2015 related to the 200 MW capacity wind project, Waiwen, since Endesa Chile determined that
the projects profitability is uncertain under current conditions. As a consequence, the project was abandoned.

These changes could
adversely affect our business, results of operations and financial condition.

Our business and profitability could be adversely
affected if water rights are denied or if water concessions are granted with limited duration.

Approximately 55% of our installed
capacity is hydroelectric. We own water rights granted by the Chilean Water Authority (Dirección General de Aguas or DGA) for the supply of water from rivers and lakes near our production facilities. Under current law,
these water rights are (i) for unlimited duration, (ii) absolute and unconditional property rights and (iii) not subject to further challenge. Chilean generation companies must pay an annual license fee for unused water rights. New
hydroelectric facilities are required to obtain water rights, the conditions of which may impact design, timing or profitability of a project.

In addition, the Chilean Congress is currently discussing amendments to the Water Code in order to prioritize the use of water by defining its
access as a human right that must be guaranteed by the State. The amendment will establish that water use for human consumption, domestic subsistence and sanitation will always take precedence, in both the granting and limiting the exercise of
rights of exploitation. Under the proposal: (i) water use concessions would be limited to 30 years, which would be extendable with respect to water rights actually used during the 30-year period, unless the Chilean Water Authority
demonstrates the water rights have not been used effectively; (ii) new non-consumptive water rights would expire if the holder does not exercise the rights within eight years; (iii) existing non-consumptive water rights which have not been
used would expire within eight years from the date of enactment of the new Water Code; and (iv) late in 2015, a new requirement regarding the preservation of water flows to protect the ecology for existing and future water rights was added for
both consumptive and non-consumptive water use, which would reduce water availability for generation purposes. Any limitations on our current water rights, our need for additional water rights, or our current unlimited duration of water concessions
could have a material adverse effect on our hydroelectric development projects and our profitability.

Any limitations on our current water rights, our need for additional water rights, or our current
unlimited duration of water concessions could have a material adverse effect on our hydroelectric development projects and our profitability.

Regulatory authorities may impose fines on our combined entities, which could adversely affect our results of operations and financial
condition.

Our electricity businesses may be subject to regulatory fines for any breach of current regulations, including energy
supply failures. In Chile, such fines may be imposed for a maximum of 10,000 Annual Tax Units ( UTA in its Spanish acronym), or Ch$ 5.4 billion using the UTA as of December 31, 2015. Our electricity generation combined entities are
supervised by local regulatory entities and may be subject to these fines in cases where, in the opinion of the regulatory entity, operational failures affecting the regular energy supply to the system are the fault of the company such as when
agents are not coordinated with the system operator. In addition, our combined entities may be required to pay fines or compensate customers if those combined entities are unable to deliver electricity, even if such failure is due to forces outside
of the combined entities control.

For example, in August 2014, the Chilean Superintendence of Environment (SMA in its
Spanish acronym) fined Endesa Chile 8,640 UTAs (approximately Ch$ 4.5 billion) for alleged environmental violations related to the Bocamina II power plant. During 2015, the Chilean Superintendence of Electricity and Fuels
(Superintendencia de Electricidad y Combustiblesor SEF) fined Chilectra Chile on five different occasions by the electricity authority for a total amount of Ch$ 4,947 million, mainly due to regulatory breaches in relation to
the quality and continuity of service during previous years and failures in two substations. Those penalties have not been paid yet, since they were appealed before the electricity authority and courts of justice. For further information on fines,
please refer to Note 37 of the Notes to our combined financial statements.

We depend on payments from our combined entities,
jointly-controlled entities and associates to meet our payment obligations.

In order to pay our obligations, we rely on cash from
dividends, loans, interest payments, capital reductions and other distributions from our combined entities. The ability of our combined entities to pay dividends, interest payments, loans and other distributions to us is subject to legal constraints
such as dividend restrictions, fiduciary duties and contractual limitations that may be imposed by local authorities.

Historically, we
have been able to access the cash flows of our combined entities, but future economic and political uncertainties, such as government regulations, economic conditions and credit restrictions, could affect our future results from operations, and
therefore we may not be able to rely on cash flows from operations in those entities to repay our debt.

Dividend Limits and Other
Legal Restrictions. The ability of any of our combined entities that are not wholly-owned to distribute cash to us may be limited by the directors fiduciary duties of such combined entities to their minority shareholders. Furthermore, some
of our combined entities may be forced by law, in accordance with applicable regulation, to diminish or eliminate dividend payments. As a consequence of such restrictions, our combined entities could, under certain circumstances, be impeded from
distributing cash to us.

Contractual Constraints. Distribution restrictions included in certain credit agreements of our combined
entities may prevent dividends and other distributions to shareholders if they are not in compliance with certain financial ratios. Generally, our credit agreements prohibit any type of distribution if there is an ongoing default.

Operating Results of Our Combined Entities. The ability of our combined entities to pay dividends or make loan payments or other
distributions to us is limited by their operating results. To the extent that the cash requirements of any of our combined entities exceed their available cash, the combined entity will not be able to make cash available to us.

Any of the situations described above could adversely affect our business, results of operations and financial condition.

Foreign exchange risks may adversely affect our results and the U.S. dollar value of
dividends payable to ADS holders.

The Chilean peso has been subject to devaluations and appreciations against the U.S. dollar and
may be subject to significant fluctuations in the future. Historically, a significant portion of our combined indebtedness has been denominated in U.S. dollars. Although a substantial portion of our operating cash flows is linked to
U.S. dollars (primarily coming from the generation business), we generally have been and will continue to be materially exposed to fluctuations of the Chilean peso against the U.S. dollar because of time lags and other limitations to peg our
tariffs to the U.S. dollar.

A substantial portion of our operating cash flows is linked to U.S. dollars, and we, as well as our combined
entities, seek to maintain debt in the same currency, but due to market conditions it may not be possible to do so. Because of this exposure, the cash generated by our combined entities can decrease substantially due to devaluations against the U.S.
dollar. Future volatility in the exchange rate of the currency in which we receive revenues or incur expenditures may adversely affect our business, results of operations and financial condition.

We are involved in litigation proceedings.

We are currently involved in various litigation proceedings, which could result in unfavorable decisions or financial penalties against us. We
will continue to be subject to future litigation proceedings, which could cause material adverse consequences to our business.

Our
financial condition or results of operations could be adversely affected if we are unsuccessful in defending lawsuits and proceedings against us. For further information on litigation proceedings, please see Note 36.3 of the Notes to our combined
financial statements.

The values of our generation businesss combined entities long-term energy supply contracts are
subject to fluctuations in the market prices of certain commodities and other factors.

We have economic exposure to fluctuations
in the market prices of certain commodities as a result of the long-term energy sales contracts into which we have entered. We and our combined entities have material obligations as selling parties under long-term fixed-price electricity sales
contracts. Prices in these contracts are indexed according to different commodities, the exchange rate, inflation, and the market price of electricity. Adverse changes to these indices would reduce the rates we charge under our long-term fixed-price
electricity sales contracts, which could adversely affect our business, results of operations and financial condition.

Our
controlling shareholder may exert a substantial influence over us and may have a different strategic view for our development than that of our minority shareholders.

Enel beneficially owns 60.6% of our share capital. Enel, our ultimate controlling shareholder, has the power to determine the outcome of
substantially all material matters that require shareholder votes, such as the election of the majority of our board members and, subject to contractual and legal restrictions, our dividend policy. Enel also exercises decisive influence over our
business strategy and operations. Its interests may in some cases differ from those of our minority shareholders. For example, Enel conducts its business operations in the field of renewable energies in Chile through Enel Green Power S.p.A. and in
South America electricity business through Enersis Américas, in neither of which we have equity interests. Any present or future conflict of interest affecting Enel may be resolved against our best interests in these matters. As a
consequence, our growth may be potentially limited, and our business and results of operations may be adversely affected.

Environmental regulations and other factors may cause delays, impede the development of new projects or increase the costs of operations
and capital expenditures.

Our operating combined entities are subject to environmental regulations which, among other things,
require us to perform environmental impact studies for future projects and obtain permits from both local and national regulators. The approval of these environmental impact studies may take longer than planned and may be withheld by governmental
authorities. Local communities and ethnic and environmental activists, among others, may intervene in the approval process to delay or prevent a projects development. They may also seek injunctive or other relief, which could negatively impact
us if they are successful.

Environmental regulations for existing and future generation capacity may become stricter, requiring increased
capital investments. For example, Decree 13 of the Chilean Ministry of the Environment, which was promulgated in January 2011 and published in June 2011, defined stricter emission standards for thermoelectric plants that must be met between
2014 and 2016, and stricter standards for new facilities or additional capacity. This regulation also requires the establishment of a system of continuous emission monitoring, pursuant to which thermoelectric plants must implement a monitoring
system in accordance with the guidelines



22

##### Table of Contents

and protocols issued by the Chilean Superintendence of the Environment. Failure to certify the implementation of such monitoring system may result in penalties and sanctions. In September 2014,
the Chilean government enacted Law 20,780 (a tax reform law), which established an annual tax on stationary power generators, such as thermal generators, tied to their emission of pollutants for the previous year. When this provision of the law
enters into force in 2018, it will apply to generators with a capacity of at least 50 MW. In compliance with these Chilean environmental regulations, all thermal plants are expected to incur in incremental investments so as to comply with the
new regulations by installing abatement systems to control pollutant emissions. Any delay in the filing may constitute a violation of the regulations which established emission limits effective on June 23, 2015 or June 23, 2016 depending
on the plants location.

In addition to environmental matters, there are other factors that may adversely affect our ability to
build new facilities or to complete projects currently under development on time, including delays in obtaining regulatory approvals, shortages or increases in the price of equipment, materials or labor, strikes, adverse weather conditions, natural
disasters, civil unrest, accidents, or other unforeseen events. Any such event could adversely impact our results of operations and financial condition.

For example, considering the likely rejection of the Environmental Impact Study of the Neltume project, Endesa Chile has redesigned the
discharge to the lake. As a result of the redesign, Endesa Chile recorded a write-off of Ch$ 2.7 billion in the fourth quarter of fiscal year 2015. The original Environmental Impact Study has been withdrawn and there are studies underway to
file it again. This is not related to the transmission line project, which is continuing as planned.

Delays or modifications to any
proposed project and laws or regulations may change or be interpreted in a manner that could adversely affect our operations or our plans for companies in which we hold investments, which could adversely affect our business, results of operations
and financial condition.

Our business may be adversely affected by judicial decisions on environmental qualification resolutions
for electricity projects in Chile.

The amount of time necessary to obtain an environmental qualification resolution for
electricity generation or transmission projects in Chile has materially increased, primarily due to judicial decisions against such projects, environmental opposition, social criticism and government delays. This can cast doubt on the ability of a
project to obtain such approval and increase the uncertainty for investing in electricity generation and transmission projects in Chile. The uncertainty is forcing companies to reassess their business strategies as the delay in the construction of
electricity generation and transmission projects may result in a supply constraints over the next five or six years. If any plant within the system ceases operation unexpectedly, we could experience supply shortages in our system, which could lead
to power cuts. Any such event could adversely affect our business, results of operations and financial condition.

Our power plant
projects may encounter significant opposition from different groups that may delay their development, increase costs, damage our reputation and potentially result in impairment of our goodwill with stakeholders.

Our reputation is the foundation of our relationship with key stakeholders and other constituencies. If we are unable to effectively manage
real or perceived issues that could negatively impact sentiments toward us, our business, results of operations and financial condition could be adversely affected.

The development of new and existing power plants may face opposition from several stakeholders, such as ethnic groups, environmental groups,
land owners, farmers, local communities and political parties, among others, all of which may impact the sponsoring companys reputation and goodwill. For example, since December 2013, the Bocamina II power plant has encountered substantial
opposition from local fishermens unions that claim that our facility negatively affects marine life and causes pollution, which resulted in the interruption of the operation of the power plant for more than a year. On July 1, 2015,
the Bocamina II power plant resumed operations, after the approval of a new RCA in April 2015. Also, between November 23, 2015 and January 7, 2016, a new group of fishermen illegally occupied the first high-tension pylon which supports the
154 kV and 220 kV circuits owned by Transelec S.A. and serve the Bocamina I and II power plants. As a consequence, both Bocamina I and II power plants were temporarily shut down. This group claimed that they should receive the same package of
benefits that Endesa Chile granted to the rest of fishermen in the zone. The financial effects of this illegal occupation and electricity transmission interruption amounted to US$ 3.8 million (Ch$ 2.7 billion using the 2015 year end
exchange rate) of contribution margin loss between November 23, 2015 and January 7, 2016. At the level of the electrical system, this situation impacts the rising global costs of supplying demand, increasing spot prices and the anticipated
use of hydroelectric reserves, which in the coming months will not be available. Such groups and other similar groups may have the ability to block our power plants and directly affect our results.

Damage to our reputation may exert considerable pressure on regulators, creditors, and other
stakeholders and ultimately lead to projects and operations that may not be optimal, causing our share prices to drop and hindering our ability to attract or retain valuable employees, all of which could result in an impairment of our goodwill with
stakeholders.

We may be exposed to asbestos liability and additional expense related to asbestos.

Several of our facilities have asbestos present in them. In April 2015, Endesa Chile completed the removal of the identifiable asbestos from
the Bocamina I power plant. However, some Akeron Caf employees, working for the contractor removing asbestos in the power plant, reported to the regional Health Ministerial Office (Seremi in its Spanish acronym) that their health had
been affected subsequently. According to Chilean regulations, any company that removes asbestos must present a work plan, which must be approved by the Seremi and supervised by the Workers Safety Association (Mutual de Seguridad) to avoid
workers being contaminated with asbestos. After an investigation, in September 2015, the Seremi of the Bio-Bío region fined Endesa Chile for Ch$ 22 million because it did not meet the necessary requirements for the removal of asbestos.
Endesa Chile appealed the decision, which is still pending. In addition, Endesa Chile is implementing asbestos removal plans in the Tarapacá, Huasco and Ralco power plants, which processes could also be affected by similar problems.

We may have to incur additional costs to remediate and implement our asbestos control and sanitation policy, or be subject to legal actions
against us, which in turn may have a material adverse effect on our business, results of operation and financial condition.

Our
business may experience adverse consequences if we are unable to reach satisfactory collective bargaining agreements with our unionized employees.

A large percentage of our employees are members of unions and have collective bargaining agreements that must be renewed on a regular basis.
Our business, financial condition and results of operations could be adversely affected by a failure to reach agreement with any labor union representing such employees or by an agreement with a labor union that contains terms we view as
unfavorable. Chilean law provides legal mechanisms for judicial authorities to impose a collective agreement if the parties are unable to come to an agreement, which may increase our costs beyond what we have budgeted.

In addition, we employ many highly-specialized employees, and certain actions such as strikes, walk-outs or work stoppages by these employees,
could adversely impact our business, results of operations and financial condition as well as our reputation.

Interruption or
failure of our information technology and communications systems or external attacks to or breaches of these systems could have an adverse effect on our operations and results.

We depend on information technology, communication and processing systems (IT Systems) to operate our businesses, the failure of
which could adversely affect our business, results of operations and financial condition.

IT Systems are all vital to our generation
combined entities ability to monitor our power plants operations, maintain generation and network performance, adequately generate invoices to customers, achieve operating efficiencies and meet our service targets and standards. Our
distribution combined entities could also be affected adversely because they rely heavily on IT Systems to monitor their grids, billing processes for millions of customers and customer service platforms. Temporary or long-lasting operational
failures of any of these IT Systems could have a material adverse effect on our results of operations. Additionally, cyber attacks can have an adverse effect on the companys image and its relationship with the community. In the last few years,
global cyber attacks on security systems, treasury operations, and IT Systems have intensified. We are exposed to cyber-terrorist attacks aimed at damaging our assets through computer networks, cyber spying involving strategic information that may
be beneficial for third parties and cyber-theft of proprietary and confidential information, including information of our customers. During 2014, we suffered two cyber attacks perpetrated by a cyber-terrorist group, which impacted our websites. In
one case, the attack resulted in a service interruption of 90 minutes. Further cyber attacks may occur and may affect us in the future.

We rely on electricity transmission facilities that we do not own or control. If these
facilities do not provide us with an adequate transmission service, we may not be able to deliver the power we sell to our final customers.

We depend on transmission facilities owned and operated by other unaffiliated power companies to deliver the electricity we sell. This
dependence exposes us to several risks. If transmission is disrupted, or transmission capacity is inadequate, we may be unable to sell and deliver our electricity. If a regions power transmission infrastructure is inadequate, our recovery of
sales costs and profits may be insufficient. If restrictive transmission price regulation is imposed, transmission companies upon whom we rely may not have sufficient incentives to invest in expansion of their transmission infrastructure, which
could adversely affect our operations and financial results. Currently, the construction of new transmission lines is taking longer than in the past, mainly because of new social and environmental requirements that are creating uncertainty about the
probability of completing the projects. In addition, the increase of new NCRE projects is congesting the current transmission system as these projects can be built relatively quickly, while new transmission projects may take longer to be built. In
May 2014, the Chilean government announced the Energy Agenda, a plan established to create and execute a long-term energy policy, which includes amendments to the legal framework of the electricity transmission systems, mainly the interconnection
between the Chilean Central Interconnected System (SIC in its Spanish acronym) and the Northern Interconnected System (SING in its Spanish acronym).

On September 24, 2011, nearly 10 million people located in central Chile experienced a blackout (affecting more than half of
the Chilean population), due to the failure of Transelecs 220 kV Ancoa substation. The failure led to the disruption of two 500 kV transmission lines in the SIC and the subsequent failure of the remote recovery computer software used
by the independent entity that coordinates generators, transmission companies and large customers (CDEC in its Spanish acronym) to operate the grid. This blackout, which lasted two hours, exposed weaknesses in the transmission grid and
its need for expansion and technological improvements to increase the reliability of the transmission grid.

Any such disruption or
failure of transmission facilities could interrupt our business, which could adversely affect our results of operations and financial condition.

The relative liquidity and volatility of Chilean securities markets could adversely affect the price of our common stock and ADS.

Chilean securities markets are substantially smaller and less liquid than the major securities markets in the United States. In
addition, Chilean securities markets may be affected materially by developments in other emerging markets. The low liquidity of the Chilean market may impair the ability of holders of ADS to sell shares of our common stock withdrawn from the ADS
program into the Chilean market in the amount and at the price and time they wish to do so. Also, the liquidity and the market for our shares or ADSs may be affected by a number of factors including variations in exchange and interest rates, the
deterioration and volatility of the markets for similar securities and any changes in our liquidity, financial condition, creditworthiness, results and profitability.

There may not be a liquid market for our shares and ADSs.

There can be no assurance as to the liquidity of any markets that may develop for our shares or ADSs or the price at which our shares or ADSs
may trade. The Chilean securities markets are substantially smaller and less liquid than the major securities markets in the United States. In addition, the Chilean securities markets may be affected materially by developments in other emerging
markets. The low liquidity of the Chilean securities markets may impair the ability of our shareholders to sell their shares, or holders of our ADSs to sell shares of our common stock withdrawn from the ADS program, into the Chilean securities
markets in the amounts and at the prices and times they wish to do so. Also, the liquidity and the market for our shares or ADSs may be affected by a number of factors including variations in exchange and interest rates, the deterioration and
volatility of the markets for similar securities and any changes in our liquidity, financial condition, creditworthiness, results and profitability. As a result, the initial trading prices of our shares and ADSs may not be indicative of future
trading prices. In addition, trading volumes of our shares and ADSs, in the aggregate, may be significantly less liquid than trading volumes of Enersis S.A.s shares and ADSs before the Spin-Off.

Enersis S.A.s historical performance is not be representative of our performance as a separate company.

Our combined financial statements are based on the historical results of operations and historical bases of the assets and liabilities of the
former Chilean businesses of Enersis S.A. Our historical performance would have been different if it had been a separate, entity during the periods presented. The historical carve-out financial information included in this Report is not indicative
of what our results of operations, financial position and cash flows will be in the future. There will be changes that will occur in our cost structure, funding and operations as a result of our separation from Enersis S.A., including increased
costs associated with reduced economies of scale, and increased costs associated with being a stand-alone publicly traded company.

Lawsuits against us brought outside Chile or complaints against us based on foreign legal
concepts may be unsuccessful.

All of our assets are located outside of the United States. All of our directors and officers
reside outside of the United States and most of their assets are located outside the United States as well. If any investor were to bring a lawsuit against our directors, officers or experts in the United States, it may be difficult for them to
effect service of legal process within the United States upon these persons, or to enforce against them, in United States or Chilean courts, judgments obtained in United States courts based upon the civil liability provisions of the federal
securities laws of the United States. In addition, there is doubt as to whether an action could be brought successfully in Chile on the basis of liability based solely upon the civil liability provisions of the United States federal securities laws.

We are an electricity utility company engaged, through our combined entities and affiliates, in the
generation, transmission and distribution of electricity businesses in Chile. We trace our origins to Compañía Chilena de Electricidad Ltda. (CCE), which was formed in 1921 as a result of the merger of Chilean Electric
Tramway and Light Co., founded in 1889, and Compañía Nacional de Fuerza Eléctrica (CONAFE), with operations dating back to 1919. In 1970, the Chilean government nationalized CCE. During the 1980s, the sector was
reorganized through the Chilean Electricity Law, CCEs operations were divided into one generation company, a currently unrelated company, and two distribution companies, one with a concession in the Valparaíso Region, and the other, our
predecessor company, with a concession in the Santiago metropolitan region. From 1982 to 1987, the Chilean electric utility sector went through a process of re-privatization. In August 1988, our predecessor company changed its name to Enersis S.A.
and became the new parent company of Distribuidora Chilectra Metropolitana S.A., later renamed Chilectra S.A. In the 1990s, Enersis S.A. diversified into electricity generation and transmission through our increasing equity stakes in Endesa Chile.

In the Extraordinary Shareholders Meeting (ESM) held on December 18, 2015, shareholders of Enersis S.A. (which
changed its name to Enersis Américas S.A. on March 1, 2016) agreed to carry out a spin-off in order to separate the Chilean activities from those in other Latin American countries (Argentina, Brazil, Colombia and Peru). We were
newly established as a separate company and were assigned the former equity interests, assets and associated liabilities of the Enersis Américas businesses in Chile effective as of March 1, 2016 and
Enersis Américas, the continuing company, now holds only the non-Chilean businesses and assets. On April 21, 2016, Enersis Américas distributed to its shareholders shares of our Company in proportion to their share
ownership in Enersis Américas based on a ratio of one share of our Company for each outstanding share of Enersis Américas.

Each of Endesa Chile and Chilectra S.A. also conducted a demerger to separate Endesa Chile and Chilectra S.A. into two companies. As part
of the demerger, Endesa Américas S.A. (Endesa Américas) and Chilectra Américas S.A. (Chilectra Américas) were created on March 1, 2016, and hold the non-Chilean business comprised of
their respective ownership interests in shares of companies domiciled outside of Chile, formerly held by Endesa Chile and Chilectra S.A, respectively.

Enel beneficially owns 60.6% of our Company and the minority shareholders of Enersis Américas own their respective percentage
interest in our Company. Our shares are listed and traded on the Chilean Stock Exchanges and our ADRs are listed and traded on the NYSE.

As of December 31, 2015, we had 6,351 MW of installed capacity with 111 generation units in Chile, combined assets of
Ch$ 5,325.5 billion and operating revenues of Ch$ 2,399 billion.

Capital Investments, Capital Expenditures and Divestitures

We coordinate our overall financing strategy, including the terms and conditions of loans and intercompany advances entered into by our
combined entities, in order to optimize debt and liquidity management. Generally, our operating combined entities independently plan capital expenditures financed by internally generated funds or direct financings. One of our goals is to focus on
investments that will provide long-term benefits, such as energy loss reduction projects. Although we have considered how these investments will be financed as part of our budget process, we have not committed to any particular financing structure,
and investments will depend on the prevailing market conditions at the time the cash flows are needed.

Our investment plan is flexible
enough to adapt to changing circumstances by giving different priorities to each project in accordance with profitability and strategic fit. Investment priorities are currently focused on developing additional hydroelectric and thermal capacity to
guarantee adequate levels of reliable supply while remaining focused on the environment.

For the 2016-2020 period, we expect to make
capital expenditures of Ch$ 1,304 billion in our combined entities, related to investments currently in progress, maintenance of our distribution network, maintenance of existing generation plants and in the studies required to develop other
potential generation and distribution projects. For further detail regarding these projects please see Item 4. Information on the Company D. Property, Plant and Equipment Projects Under Development.

The table below sets forth the expected capital expenditures for the 2016-2020 period and the capital expenditures incurred in 2015, 2014 and
2013:

| | --- | ----------------------------------------------------------------------------------------

Capital Expenditures for 2015, 2014 and 2013

Our capital expenditures in the last three years were related principally to the 350 MW Bocamina II power plant and the 150 MW Los
Cóndores power plant. Bocamina II began commercial operations in October 2012. Subsequently, Bocamina II suspended operations in December 2013 due to environmental injunctions and reassumed operations in July 2015. Los Cóndores is a
hydroelectric project, which began construction in 2014 with completion expected in 2018.

Investments currently in progress

In our generation business, material plans in progress include the 150 MW Los Cóndores project described above. A portion of our
capital expenditure is reserved for the maintenance the quality and operation standards of our facilities.

In our distribution business,
we plan to continue to expand our services and reduce energy losses to improve the efficiency of our facilities and profitability of our business. Our current distribution projects seek to increase the connections available to end customers.

Projects in progress will be financed with resources provided by external financing as well as internally generated funds.

##### Table of Contents

In the electricity industry, it is common to segment the business into hydroelectric and
thermoelectric generation because each type of generation has significantly different variable costs. Thermoelectric generation requires the purchase of fuel, which leads to a high variable costs compared with hydro generation from reservoirs or
rivers that have no marginal costs. Of our total combined generation in 2015, 64.7% was from hydroelectric sources, 34.5% was from thermal sources, and less than 1% was from wind energy, which is generated by the Canela I and Canela II wind farms,
which are subsidiaries of Celta.

The following table summarizes our combined generation by type of energy:

The
potential for contracting electricity is generally related to electricity demand. Customers identified as small volume regulated customers, including residential customers, are subject to government regulated electricity tariffs and must purchase
electricity directly from a distribution company. These distribution companies, which purchase large amounts of electricity for small volume residential customers, generally enter into contractual agreements with generators at a regulated tariff
price. Those identified as large volume industrial customers also enter into contractual agreements with energy suppliers. However, such large volume industrial customers are not subject to the regulated tariff price. Instead, these customers are
allowed to negotiate the energy price with generators based on the characteristics of the service required. Finally, the pool market, where energy is normally sold at the spot price, is not carried out through contracted pricing.

The following table contains information regarding our combined sales of electricity by type of customer for each of the periods indicated:

Specific energy
consumption limits (measured in GWh) for regulated and unregulated customers are established. Moreover, regulatory frameworks often require that regulated distribution companies have contracts to support their commitments to small volume customers
and also determine which customers can purchase energy in electricity pool markets.

##### Table of Contents

In terms of expenses, the primary variable costs involved in the electricity generation business,
in addition to the direct variable cost of generating hydroelectric or thermal electricity such as fuel costs, are energy purchases and transportation costs. During periods of relatively low rainfall conditions, the amount of our thermal generation
increases. This involves an increase of the total fuel cost and the costs of its transportation to the thermal generation power plants. Under drought conditions, electricity that we have contractually agreed to provide may exceed the amount of
electricity that we are able to generate, which requires us to purchase electricity in the pool market at spot prices in order to satisfy our contractual commitments. The cost of these purchases at spot prices may, under certain circumstances,
exceed the price at which we sell electricity under contracts and, therefore, may result in a loss. We attempt to minimize the effect of poor hydrological conditions on our operations in any year by limiting our contractual sales requirements to a
quantity that does not exceed the estimated production in a dry year. To determine an estimated production in a dry year, we take into consideration the available statistical information concerning rainfall, hydrological levels, and the capacity of
key reservoirs. In addition to limiting contracted sales, we may adopt other strategies including installing temporary thermal capacity, negotiating lower consumption levels with unregulated customers, negotiating with other water users and
including pass-through cost clauses in contracts with customers.

Seasonality

While our core businesses are subject to weather patterns, generally only extreme events such as prolonged droughts, which may adversely
affect our generation capacity, rather than seasonal weather variations, may materially affect our operating results and financial condition.

The distribution business is directly influenced by seasonal changes in energy demand. Although the price at which a distribution company
purchases electricity can change seasonally and has an impact on the price at which it is sold to end users, it does not have an impact on our profitability since the cost of electricity purchased is passed to end users through tariffs that are set
for multi-year periods. During 2015, the effects of average temperatures (neither extremely cold nor hot) in Santiago negatively impacted our residential customers per capita consumption, which represented 27% of our electricity distribution
during 2015. Moderate temperatures reduce the need for heating and air conditioning. Lower economic activity was reflected in the consumption of the commercial and industrial segments. The month with the greatest energy demand typically is July (9%
higher than the yearly average), due to heating in winter, and the month with the lowest consumption is typically February (9% less than the yearly average) due to it having fewer days and because many residential customers are on vacation outside
our concession area in summer, resulting in lower economic activity.

The generation business is also affected by seasonal changes
throughout the year. During normal hydrological years, snow melts typically occur during the warmer months of October through March. These snow melts increase the level in our reservoirs. The months with most precipitation are typically May through
August.

When there is more precipitation hydroelectric generating facilities can accumulate additional water to be used for generation.
The increased level of our reservoirs allows us to generate more electricity with hydro power plants during months in which marginal electricity costs are lower.

In general, hydrological conditions such as droughts and insufficient rainfall adversely affect our generation capacity. For example, severe
prolonged drought conditions or reduced rainfall levels in Chile caused by El Niño phenomenon reduces the amount of water that can be accumulated in reservoirs, thereby curtailing our hydroelectric generation capacity. In order to
mitigate hydrological risk, hydroelectric generation may be substituted with thermal generation (natural gas, LNG, coal or diesel) and energy purchases on the spot market, both of which could result in higher costs, in order to meet our obligations
under contracts with both regulated and unregulated customers.

Operations

We own and operate a total of 111 generation units in Chile through Endesa Chile, Pehuenche, Celta and GasAtacama. Of these generation units,
38 are hydroelectric, with a total installed capacity of 3,465 MW. This represents 54.6% of our total installed capacity in Chile. There are 22 thermal generation units that operate with gas, coal or oil with a total installed capacity of
2,808 MW, representing 44.2% of our total installed capacity in Chile. There are 51 wind powered generation units with an aggregate installed capacity of 78 MW, representing 1.2% of our total installed capacity in Chile. All of our
generation units are connected to SIC, except for two of Celtas thermoelectric generation units and six of GasAtacamas thermoelectric generation units which are connected to the Northern Interconnected System (SING in its
Spanish acronym) in northern Chile.

Water Agreements

Water agreements refer to the right of a user to use water from a water source, such as a river, stream, pond or
groundwater. In times of good hydrological conditions, water agreements are generally not complicated or contentious. However, in times of poor hydrological conditions, water agreements protect our ability to use water resources for
hydroelectric generation.

Endesa Chile has two agreements in force with the purpose of utilizing water for both irrigation and
hydroelectric generation more efficiently.

These agreements between Endesa Chile and the Chilean Water Works Authority (DOH
in its Spanish acronym) are related to the water consumption during the most intense irrigation period (normally from September to April) from Laja Lake and Maule Lagoon, both located in southern Chile. Endesa Chile signed the first agreements with
the DOH with respect to Laja Lake and Maule Lagoon on October 24, 1958 and September 9, 1947, respectively. Both basins have been severely impacted by drought conditions and high consumption over the past several years. As a result, during
recent years, Endesa Chile and the DOH signed supplementary agreements that apply for special irrigation periods depending on hydrological conditions. For example, on December 9, 2015, the parties agreed on the terms for the 2015-2016
irrigation period for Laja Lake (the Laja Agreement) and on December 29, 2015 the parties entered into a similar agreement with respect to Maule Lagoon (the Maule Agreement, and together with the Laja Agreement, the
Water Agreements). The Water Agreements: (i) preserve the level of water of the reservoirs, assuring its availability for the future and (ii) satisfy the requirements for both agricultural and hydroelectric generation usage.

According to the terms of the Laja Agreement, users are allowed to draw a fixed volume from the lake, excluding filtrations, between
December 1, 2015 and November 30, 2016, for both irrigation and hydroelectric generation purposes, as follows: (i) 300 million cubic meters (mcm) for irrigation; (ii) 300 mcm for electricity generation, and
(iii) 100 mcm unrestricted use for Endesa Chile, unless the agriculture sector has a need during the months of February, March and April, with the approval of the DOH. Endesa Chile is also entitled to draw a variable volume of a
maximum of 200 mcm of water, to be executed in four installments, with a maximum of 50 mcm for each installment, depending of the level of the reservoir. Additionally, if by April 30, 2016, the amount allocated for irrigation purposes has not
been completely used, the Laja Agreement entitles Endesa Chile to draw the remaining part of the unused volume of water.

According to the
terms of the Maule Agreement, usage rights of water depend on the level of the reservoir. During the 2010-2014 period, a severe drought resulted in the reservoir reaching critically low levels and part of the irrigation usage rights being reduced.
The Maule Agreement was signed in order to give Endesa Chile the flexibility to draw water during off-season periods, when electricity spot prices are lower, and at the same time avoiding potential conflicts with local farmers, preventing riots,
roadblocks, and future litigation. Pursuant to the Maule Agreement, irrigation usage must occur during specific periods, based on the forecasted thaw conditions published by CDEC-SIC and the DOH, and the Maule River Watch Committee (JVRM
in its Spanish acronym), to prevent water deficits. Endesa Chile may partially or totally cover the irrigation deficits from the Maule Lagoon with water from the Invernada Lagoon (part of the Maule River system), replacing the required irrigation
draws from Maule Lagoon. The decision over the use of the Invernada Lagoon would be at Endesa Chiles discretion depending on its electricity generation calendar.

Endesa Chile has the ability to draw a specified amount of water for irrigation at a specific time from Invernada Lagoon, which is Endesa
Chiles property, instead of water from Maule Lagoon, which is owned by the Chilean government. In exchange, for each cubic meter of Invernada Lagoon water drawn for irrigation, Endesa Chile will receive an extra 0.82 cubic meters of water when
the Maule Lagoon level is at medium level and an extra 1 cubic meter of water when the Maule Lagoon level is at high level. During the medium level scenario, the remaining unused volume (0.18 cubic meters of water), will be stored at Maule Lagoon,
increasing the reserves of the reservoir, and will be accessible in the following season according to the rights granted to all the parties to the Maule Agreement. The decision as to when and how much to use the extra water volume is solely at
Endesa Chiles discretion, and cannot exceed 30 cubic meters of water per second per month. The Maule Agreement expires on August 1, 2018, and a new agreement will be entered into based on the conditions of the Maule River system at that
time.

Both Water Agreements will allow the two reservoirs to recover their accumulated water levels and to preserve water use for future
years. From the Companys point of view, these agreements allow Endesa Chile to use the water more efficiently, primarily in Maule Lagoon, and to avoid further litigation with the local community, especially with farmers.

Thermal Generation

Our thermal electric generation facilities use LNG, coal and to a lesser extent, diesel. This allows us to use other fuels if the price of LNG
is too high, if there is a shortage of supply, or if there is another circumstance that makes LNG unavailable. In order to satisfy our natural gas and transportation requirements, we signed long-term gas contracts with suppliers that establish
maximum supply amounts and prices, as well as long-term gas transportation agreements with the pipeline companies. Endesa Chile currently uses Gas Andes (an unaffiliated entity) and Electrogas (our associate) as our suppliers. Since March 2008, all
of Endesa Chiles natural gas units also operate using natural gas or diesel and since December 2009, San Isidro, San Isidro 2 and Quintero operate using LNG.

Endesa Chiles contract for LNG is the largest supply contract and it is based on long-term agreements with Quintero LNG Terminal
(GNLQ) for regasification services and British Gas for supply. In July 2013, Endesa Chile and British Gas renegotiated their LNG Sale and Purchase Agreement and modified some conditions of the original contract. Endesa Chiles
current LNG Sale and Purchase Agreement with British Gas runs through 2030 and is indexed to the Henry Hub/Brent commodity prices. Endesa Chile receives 29.7 TBtu of gas annually, and the contract provides the flexibility to purchase between 23.6
TBtu and 24.6 TBtu additionally, if needed. There are contingencies in the contract that would allow cancellations (for a fee), and deviations, under certain conditions. Endesa Chile is not dependent on any one particular source of LNG, as long as
the LNG meets the contracted specifications.

Endesa Chiles Terminal Use Agreement, through GNLQ, is the most relevant for Endesa
Chiles LNG supply and is sufficient to meet its current needs. This contract runs through 2035, has a fixed pricing structure of 10% return on assets plus a marketing fee and allows Endesa Chile, through GNL Chile, to access additional supply
from the spot market, if needed.

These contracts allow Endesa Chile to secure its long-term LNG supply at competitive prices, with
significant flexibility and the addition of new capacity sufficient for its current and potential needs.

Endesa Chile also exercised a
priority right to purchase additional regasification capacity as part of an expansion of GNLQ. This has allowed Endesa Chile to increase its regasification capacity from 3.2 million cubic meters per day to 5.4 million cubic meters per day
as of the date of this Report. This additional capacity will allow Endesa Chiles San Isidro and Quintero facilities to provide additional thermal generation, to secure the regasification for future power plants, as well as develop new
businesses, such as the tolling agreement signed with Gener during 2015, which has allowed Endesa Chile to utilize LNG in Geners Nueva Renca combined-cycle power plant to generate electricity.

Endesa Chile has also contracted capacity in the LNG truck loading facility (TLF) in GNLQ, which has allowed it to sell natural
gas to industrial customers. In August 2014, the first load of LNG was successfully delivered to MAERSKs satellite regasification facility, first industrial customer of Endesa Chile. During 2014, a 20-year sale and purchase agreement was
signed with GasValpo (a gas distribution company) to distribute natural gas using the TLF for new customers in various cities in Chile. The first stage began operations in August 2015, to supply the city of Talca (270 km south of Santiago).
Additionally, the TLF was used to supply the cities of Coquimbo and La Serena during November 2015 and to supply the city of Los Andes during December 2015. Other plants are currently in advanced construction and will start to operate during first
quarter of 2016.

In January 2015, an agreement with Intergas (a gas distribution company) was signed to supply LNG by trucks to the city
of Temuco (700 km south of Santiago). This supply arrangement is expected to start during May 2016.

During 2015, 723 kilotons of coal
were consumed by the Tarapacá and Bocamina power plants. Between January and September 2015, four loads of coal were received by the Tarapacá power plant (206 kilotons total), which had been deferred according to the terms of the Coal
Sale and Purchase Agreement entered into in September 2013 between Endesa Chile and Endesa Generación S.A., a Spanish subsidiary of Enel, to supply the Bocamina I and II power plants, which were stopped for 8 and 18 months respectively, until
July 2015, due to judicial issues affecting the power plants during 2013 and 2014. The cost associated with these deferrals was approximately US$ 760,000.

Under Chilean law, power generation companies must demonstrate that a minimum amount of their energy sales are from NCRE. Currently, our
Canela wind farms, Ojos de Agua mini-hydroelectric plant and 40% of the installed capacity of our Palmucho mini-hydroelectric plant qualify as NCRE facilities. We fully complied with this obligation during 2015. The additional cost of generating
electricity using NCRE facilities is being charged as a pass-through in our new contracts, which mitigates the impact to our operating income.

We supply electricity to the major regulated electricity distribution companies, large unregulated industrial firms (primarily in the mining,
pulp and steel sectors) and the pool market. Commercial relationships with our customers are usually governed by contracts. Supply contracts with distribution companies must be auctioned, and are generally standardized with an average term of ten
years.

Supply contracts with unregulated customers (large industrial customers) are specific to the needs of each customer, and the
conditions are agreed between both parties, reflecting competitive market conditions.

In 2015, 2014 and 2013, we had 41, 46 and 50
customers, respectively. In 2015, our customers included 18 distribution companies in the SIC and 23 unregulated customers.

In addition,
Endesa Chile, through its subsidiary, GasAtacama, began exporting electricity to Argentina during February 2016. This follows the signing of an agreement during October 2015. Approximately 2.3 GWh of electricity is exported per day to Argentina
using the AES Gener transmission line that connects Mejillones, Chile and Salta, Argentina. Through February 29, 2016 approximately 45 GWh had been exported to Argentina.

Our generation contracts with unregulated customers are generally on a long-term basis and typically range
from five to fifteen years. Such contracts are usually automatically extended at the end of the applicable term, unless terminated by either party upon prior notice. Some include a price adjustment mechanism in the case of high marginal costs, and
therefore, reduces the hydrological risk. Contracts with unregulated customers may also include specifications regarding power sources and equipment, which may be provided at special rates, as well as provisions for technical assistance to the
customer. We have not experienced any supply interruptions under our contracts. If we experienced a force majeure event, as defined in the contract, we are allowed to reject purchases and we have no obligation to supply electricity to our
unregulated customers. Disputes are typically subject to binding arbitration between the parties, with limited exceptions.

For the year
ended December 31, 2015, our principal distribution customers were (ordered alphabetically): CGE, Chilectra Chile, Chilquinta, Emel group and Saesa group and our principal unregulated customers were (ordered alphabetically): Caserones,
Compañia Minera Carmen de Andacollo, Compañia Minera Collahuasi, Grupo CAP-Compañía Minera del Pacifico and Minera Valle Central. The contracts with Grupo CAP-Compañía Minera del Pacifico were terminated on
December 31, 2015.

We compete in the SIC primarily with two generation companies, AES Gener S.A. (Gener) and
Colbún. According to the CDEC-SIC in 2015, in the SIC, Colbún had an installed capacity of 3,305 MW, of which 53.2% was thermoelectric and Gener and its subsidiaries had an installed capacity of 2,736 MW, of which 89.7% was
thermoelectric. In addition, there are a number of smaller entities with an aggregate installed capacity of 4,483 MW that generate electricity in the SIC.

As of December 31, 2015, our primary competitors in the SING were E-CL (GDF Suez Group) and Gener, which have 2,147 MW and
822 MW of installed capacity, respectively. Our direct participation in the SING includes our 182 MW Tarapacá thermal plant, owned by our combined entity Celta, and the 780 MW GasAtacama thermal plant.

Electricity generation companies compete largely on the basis of price, technical experience and reliability. In addition, because 64.3% of
our installed capacity in the SIC is from hydroelectric power plants, we have lower marginal production costs than companies generating electricity through thermal plants. Our installed thermal capacity benefits from access to gas from the GNLQ.
However, during periods of extended droughts, we may be forced to buy more expensive electricity from thermoelectric generators at spot prices in order to comply with our contractual obligations.

Directly and through our combined entities, we are the principal generation operator in the SIC, with 33.9% of the total installed capacity
and 42.6% of the electricity energy sales in this system in 2015.

In the SING, our combined entities, Celta and GasAtacama, accounted for
23.2% of the total installed capacity and 14.4% of the electricity energy sales in this system in 2015.

Industry Overview Industry Structure

The Chilean electricity industry is divided into three business segments: generation, transmission and distribution. These business segments
are carried out by publicly-owned private sector companies, in which generators can also trade energy with unregulated customers. The states role is circumscribed to regulation, supervision and indicative investment planning through
non-binding recommendations in the case of generation and transmission. However, the indicative investment planning and construction bidding processes of the transmission system are binding.

The following chart shows the relationships among the various participants in the Chilean electricity market:



LOGO

The generation segment is comprised of a group of electricity companies that own generating plants, whose
energy is transmitted and distributed to end customers. This segment is characterized by being a competitive market which operates under market-driven conditions. Generation plants sell their energy to distribution companies, unregulated customers
and other generation companies, and their surpluses on the spot market.

##### Table of Contents

The transmission segment is comprised of a combination of lines, substations and equipment for
the transmission of electricity from the production points (generators) to the centers of consumption or distribution. Transmission in Chile is defined as lines or substations with a voltage or tension higher than 23 kV. The transmission system is
open access, and transmission companies may impose rights of way over the available transmission capacity through the payment of tolls.

The distribution segment is defined for regulatory purposes as all electricity supplied to end customers at a voltage no higher than 23 kV.
Distribution companies operate under a distribution public utility concession regime, with service obligations and regulated tariffs for supplying regulated customers.

Customers are classified according to their demand, as follows: (i) unregulated customers with connected capacity of over 2,000 kW;
(ii) regulated customers with connected capacity of no more than 500 kW; and (iii) customers that choose either a regulated tariff or an unregulated regime, for a minimum period of four years, available to customers whose connected
capacity falls in the range of 500 kW to 2,000 kW. In January 2015, Chilean Congress approved a reform of the procurement system contained in the Chilean Electricity Law (described below), which becomes effective in 2019 and will raise the capacity
limit for unregulated customers from 2,000 kW to 5,000 kW and will lower the minimum capacity from 2,000 kW to 500 kW.

The distribution
companies supply regulated customers, a segment for which the price and supply conditions are the result of tender processes regulated by the CNE, and unregulated customers, with bilateral agreements between generators, whose conditions are freely
negotiated and agreed upon.

In Chile, there are four separate interconnected electricity systems. The main systems that cover the most
populated Chilean areas are the SIC, which services the central and south central part of the country, where 92.2% of the Chilean population lives, and the SING, which operates in the northern part of the country, where most of the mining industry
is located and where 6.3% of the Chilean population lives (2014 CDEC-SIC annual report). In addition to the SIC and the SING, there are two isolated systems in southern Chile that provide electricity to remote areas, where 1.5% of the population
lives.

In 2013, the Chilean government sent a proposal to modify the Chilean Electricity Law to allow the state to promote the
interconnection project between the SIC and the SING. In January 2014, the proposal was approved and signed into law by the Chilean President as Law No. 20,726. The interconnection, which is being built by GDF SUEZ is expected to be completed
in by 2019.

In May 2014, the Chilean government announced the Energy Agenda in which a plan was established to create and execute a
long-term energy policy. The Energy Agenda presents several courses of action and goals to achieve in the short, medium and long term. These objectives are: lower energy prices, facilitating the incorporation of non-conventional renewable energy
sources and promoting the efficient use of energy.

The Energy Agenda includes a program of legal initiatives to realize those goals.
Among the subjects to be addressed by this program are: Amendments to the legal framework for procurement of electricity for regulated customers (approved and published in the Diario Oficial in January 2015), Amendments to
the legal framework of the electricity transmission systems (presented to Congress in August 2015, currently under study, and expected to be enacted during the third quarter of 2016), Energy Efficiency Law (expected to be enacted
during fourth quarter of 2016) and Law to promote geothermal energy (expected to be enacted during the fourth quarter of 2016).

As part of the energy agenda, Decree No. 148 (Energía 2050 Política Energética de Chile) was
signed on December 30, 2015. Decree No. 148 approves the new long-term strategy for the electricity sector, which aims to (i) improve electricity service for the impoverished, (ii) have 70% of national electricity generation
from NCRE and (iii) ensure that 100% of new construction to be built with energy control systems and smart energy management by 2050.

For more information about the amendments, see The Electricity Law  General below.

The operation of electricity generation companies in each of the two major interconnected electricity systems is coordinated by their
respective dispatch centers, known as a CDEC, an independent entity that coordinates generators, transmission companies and large customers. CDEC coordinates the operation of its system with an efficiency criterion in which the lowest cost producer
available is usually required to satisfy demand at any moment in time. As a result, at any specific level of demand, the appropriate supply will be provided at the lowest possible production cost available in the system. The marginal cost used is
the price at which generators trade energy on an hourly basis, involving both their injections into the system and their withdrawals or purchases for supplying their customers.

Principal Regulatory Authorities

The Chilean Ministry of Energy develops and coordinates plans, policies and standards for the proper operation of the sector, approves tariffs
and node prices set by the CNE, and regulates the granting of concessions to electricity generation, transmission and distribution companies. The CNE is the technical entity in charge of defining prices, technical standards and regulatory
requirements.

The SEF monitors the proper operation of electricity, gas and fuel sectors in compliance with the law in terms of safety,
quality, and technical standards.

The Chilean Ministry of Environment is responsible for the development and application of regulatory
and policy instruments that provide for the protection of natural resources, the promotion of environmental education and the control of pollution, among other matters. It is also responsible for administering the environmental impact assessment
system at the national level, coordinating the preparation of environmental standards and establishing the programs for compliance with the standards.

Chilean antitrust authorities are responsible for preventing, investigating and correcting any threats to free market competition and any
anti-competitive practices by potentially monopolistic companies. These authorities include:



| |  |  | Free Market Competition Tribunal (TDLC in its Spanish acronym). This is a special and independent jurisdictional entity, subject to the directive, correctional and economic authority of the Chilean Supreme
Court, which functions to prevent, correct and sanction threats to free market competition.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | National Economic Prosecutor (FNE in its Spanish acronym). This is the attorney general responsible for economic matters and for investigating and prosecuting all antitrust conduct before the FNEs
regulatory commission and other tribunals.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The Panel of Experts acts as a tribunal in electricity matters arising from
disputes between participants in the electricity market and between participants in the electricity market and the regulatory authority in certain tariff processes. It issues enforceable resolutions and is composed of experts in industry matters,
five engineers or economists and two lawyers, all of whom are elected every six years by the TDLC.

There are also other entities related
to the energy sector: the Chilean Nuclear Energy Commission is in charge of research, development, use and control of nuclear energy and the Chilean Energy Efficiency Agency is in charge of promoting energy efficiency.

The Electricity Law

General

Since its inception, the Chilean electricity industry has been developed by private sector companies. Nationalization was carried out during
the period from1970 to1973. During the 1980s, the sector was reorganized through the Chilean Electricity Law, known as DFL 1, allowing participation of private capital in the electricity sector. By the end of the 1990s, foreign companies had a
majority participation in the Chilean electricity system.

The goal of the Chilean Electricity Law is to provide incentives to maximize
efficiency and to provide a simplified regulatory scheme and tariff-setting process that limits the discretionary role of the government by establishing objective criteria for setting prices. The goal is an economically efficient allocation of
resources. The regulatory system is designed to provide a competitive rate of return on investment to stimulate private investment, while ensuring the availability of electricity to all who request it.

DFL 1 was published in 1982 and has had few important changes since then to deal with droughts, encourage investments in transmission lines
and to create long-term contracts between generation and distribution companies as part of a bid process. The present text of the law was restated as DFL 4 of 2006, and has been supplemented with a series of regulations and standards.

In January 2015, the Chilean Congress approved amendments to the legal framework for procurement of electricity by regulated customers. Among
the principal changes introduced in these amendments, were:



| | ● |  | Increased CNE participation in the development of tenders.
| | - |  | ----------------------------------------------------------



| | ● |  | Additional time to call for tenders: five years in advance.
| | - |  | -----------------------------------------------------------



| | ● |  | Allocation mechanism: Will be awarded to the lowest prices offered. These prices will be limited by a capped price that will be deemed as a reserve price and keep private until the bid price is public.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| | ● |  | Reduced risk: Providers of electricity have the ability to postpone delivery of electricity in the event there are delays due to well-founded reasons not attributable to the tenderer and to request a price review,
indexed to the conditions prevalent at the time which the supply is delivered.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | Short-term contracts: Short-term procurement contracts (up to three years), with an advance of one year, have a minimum price equal to the average market price plus 50%. Additionally, within specified ranges from the
average marginal cost price, marginal cost will be used.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | Uncontracted energy: All generators within a particular system will be required to offset energy supply contract deficits in proportion to the energy they inject into the system. Each generator will receive the higher
of the short-term node price or variable cost of the plant. When energy without contracts exceeds 5% of the total regulated supply, the excess will be paid by distribution companies at a price equal to marginal cost. In turn, these marginal costs
will be passed on to end customers.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | Unregulated customers: Unregulated customers capacity limit increased from 2,000 kW to 5,000 kW beginning 2019.
| | - |  | ---------------------------------------------------------------------------------------------------------------

Currently, a new modification is under study by the Chilean Congress and is expected to be enacted during the second quarter of 2016, with the
purpose of addressing two issues:



| | ● |  | Planning the expansion and remuneration of the Chilean transmission systems.
| | - |  | ----------------------------------------------------------------------------



| |  |  | Long-term energy planning for terms of at least 40 years by the Chilean Ministry of Energy.
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | Annual transmission system planning by the CNE.
| | - |  | -----------------------------------------------



| |  |  | Transmission network valuation process every four years.
| | - |  | --------------------------------------------------------



| | ● |  | Transmission network cost to be financed by unregulated and regulated consumers. The creation of a new entity to coordinate the power plant operations and the transmission facilities of the Chilean electricity system
(Comité Independiente del Sistema Eléctrico Nacional,CISEN in its Spanish acronym)
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Independent power plant directory.
| | - |  | ----------------------------------



| |  |  | Attributions and resources
| | - |  | --------------------------



| |  |  | In the middle-term, due to the SING-SIC interconnection, there will be only one new operator of the Chilean electricity system.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------

Limits and Restrictions

The
owners of the main transmission system must be constituted as limited liability stock corporations and cannot take part in the electricity generation or distribution businesses.

Individual interest in the Main Transmission System (STT in its Spanish acronym) by companies operating in another electricity or
unregulated customer segment cannot exceed, directly or indirectly, 8% of the total investment value of the STT. The aggregate interest of all such agents in the STT must never exceed 40% of the investment value.

According to the Chilean Electricity Law, there are no restrictions on market concentration for generation and distribution activities.
However, Chilean antitrust authorities have imposed certain measures to increase the transparency within the different companies within the group of Enersis S.A. and its subsidiaries. The TDLCs Resolution No. 667/2002 requires:



| | ● |  | board members of Enersis S.A., Empresa Nacional de Electricidad S.A. and Chilectra S.A. be elected from different and independent groups;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | the external auditors of Enersis S.A., Empresa Nacional de Electricidad S.A. and Chilectra S.A. be different for local statutory purposes;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | Enersis S.A., Empresa Nacional de Electricidad S.A. and Chilectra S.A. may not merge companies within the group which operate in electricity generation and distribution; instead, Enersis must continue to maintain both
business segments separately through companies that are independent business units; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | Enersis S.A., Empresa Nacional de Electricidad S.A. and Chilectra S.A. must remain subject to the regulatory authority of the SVS and comply with the regulations applicable to publicly held stock corporations, even if
they should lose such designation.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

Resolution No. 667/2002 applies to Enersis Chile, as stated in its by-laws, although the
restrictions of Resolution No. 667/2002 are not applicable between Enersis Chile and Enersis Américas.

Enersis
Américas, as the continuing company of Enersis S.A., is subject to the restrictions of Resolution No. 667/2002. However, as stated in their by-laws, these restrictions are not applicable between Enersis Chile and Enersis Américas.
In addition, these restrictions do not apply between Enersis Americas, Endesa Americas and Chilectra Américas because Enersis Américas does not participate in any way in the relevant markets within Chile.

Additionally, in October 2012, FNE Official Letter No. 1479 imposed additional restrictions on Empresa Nacional de Electricidad S.A.,
which are still applicable to Endesa Chile and Chilectra Chile after the spin-offs, stating that:



| | ● |  | the controlling shareholders should refrain from designating those persons who had been directors of Chilectra Chile during the prior term as Endesa Chile directors; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | Endesa Chiles management should refrain from designating employees in first and second level positions that had held the same positions in Chilectra Chile during the six months prior to their designation.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In addition, the Water Utility Services Law also sets restrictions on the overlapping of concessions in the same area,
setting restrictions on the ownership of the property for water and sewage service concessions and utilities that are natural monopolies, such as electricity distribution, gas or home telephone networks.

Regulation of Generation Companies Concessions

Chilean law permits generation activity without a concession. However, companies may apply for a concession to facilitate access to
third-party properties. Third-party property owners are entitled to compensation, which may be agreed to by the parties or, if there is no agreement, it may be determined by an administrative proceeding that may be appealed in the Chilean courts.

Dispatch and Pricing

In
each of the two major electric systems, the pertinent CDEC coordinates the operations of generation companies, in order to minimize the operating costs in the electricity system and monitor the quality of service provided by the generation and
transmission companies. Generation companies satisfy their contractual sales requirements with dispatched electricity, whether produced by them or purchased from other generation companies in the spot market.

Sales by Generation Companies to Unregulated Customers

Sales by generation companies may be made to unregulated end customers or to other generation companies under freely negotiated contracts. To
balance their contractual obligations with their dispatch, generators have to trade deficit and surplus electricity at the spot market price, which is set hourly by each CDEC, based on the lowest cost of production of the last kWh dispatched.

Sales to Distribution Companies and Certain Regulated Customers

Under Law No. 20,018 (Ley Corta II), enacted on May 19, 2005, all new contracts between generation and distribution companies
to supply electricity to regulated customers must arise from international bids. In January 2015, the Diario Oficial published Law No. 20,805, which amended the bidding process for supplying electricity to regulated customers. These
amendments, among others, changed the anticipation required for the bidding process from three to five years; extended the maximum contract period from 15 to 20 years; adopted a capped price known as reserve price that is kept private
until the bid price is made public; and allowed for the possibility to review the price awarded during the supply period, setting new procedures to assign energy without contracts and to regulate the short-term bidding process.

Sales of Capacity to Other Generation Companies

Each CDEC determines a firm capacity for each power plant on an annual basis. Firm capacity is the highest capacity which a generator may
supply to the system at certain peak hours, taking into consideration statistical information and accounting for time out of service for maintenance purposes and for extremely dry conditions in the case of hydroelectric plants.

##### Table of Contents

A generation company may be required to purchase or sell capacity in the spot market, depending
upon its contractual requirements in relation to the amount of electricity to be dispatched from such company and to its firm capacity.

Promotion
of Generation from Renewable Energy Sources

On April 1, 2008, Law No. 20,257 amended the General Electric Services Law.
The purpose of the amendment was to promote the development of NCRE. This law defines the different types of technologies that qualify as NCRE and establishes the obligation for generators, between 2010 and 2014, to supply at least 5% of the total
energy contracted as of August 31, 2007, to be of a certain type, and to progressively increase this percentage by 0.5 percentage points annually up to a minimum of 10% by 2024.

On October 22, 2013, Law No. 20,698 was adopted to promote the use of NCRE and modify the previously defined NCRE minimum
requirements. This law establishes a mandatory share of renewable energy sources in 2025, calculated as a percentage of the total contracted energy of each generator. For contracts signed between 2007 and 2013, the target is 10% by 2024, while for
contracts beyond 2013 the target is 20% by 2025.

Incentives and Penalties

If a rationing decree is enacted in response to prolonged periods of electricity shortages, strict penalties may be imposed on generation
companies that contravene the decree. A severe drought is not considered a force majeureevent under our service agreements.

Generation companies may also be required to pay fines to the regulatory authorities, as well as compensate electricity customers affected by
shortages of electricity. The fines are related to system blackouts due to an electricity generators operational problems, including failures related to the coordination duties of all system agents. If generation companies cannot satisfy their
contractual commitments to deliver electricity during periods when a rationing decree is in effect and there is no energy available to purchase in the system, the generation company must compensate the customers at a rate known as the failure
cost determined by the authority in each node price setting. This failure cost, which is updated semiannually by the CNE, is a measurement of how much end customers would pay for one extra MWh under rationing conditions.

Water Rights

Companies in Chile must
pay an annual fee for unused water rights. License fees already paid may be recovered through monthly tax credits commencing on the start-up date of the project associated with the water right. The maximum license fees that may be recovered are
those paid during the eight years before the start-up date.

The Chilean Constitution considers water as a national public good on which
real utilization rights are defined. That is similar to holding the private property rights over water, as set forth in article 19, paragraph 24: The rights of individuals over water, recognized or constituted in accordance with the law, grant
their holders ownership over such rights. Notwithstanding the foregoing, paragraph 24 also specifies legal limitations to those water rights.

The Chilean Congress is currently discussing amendments to the Water Code with the objective of making water use related to human consumption,
household subsistence and sanitation a priority. The amendments are currently in the first stage of the legislative process in the Chilean House of Representatives and have been approved by the Mining and Energy Commission and are currently being
evaluated by the Agricultural Commission. The main aspects of the amendments are as follows:



| | ● |  | Granting of water rights which would be limited to a maximum period of 30 years and extendable, unless the Chilean Water Authority proves the ineffective use of resources. The extension shall be effective only for used
water rights.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | The expiration of non-consumptive water rights that were granted by law, if the holder does not exercise the right of use within eight years.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | The expiration of non-consumptive water rights already granted, if the user does not effectively use the rights within a period of eight years from the date of enactment of the new Water Code. Only in justified cases,
such as delays in obtaining permits or environmental approvals, can the term be extended for up to four years.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | Late in 2015, there was a new requirement regarding the preservation of water flows to protect the ecology for existing and future water rights for both consumptive and non-consumptive water use, which would reduce the
water availability for generation purposes.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Regulation of Distribution Companies

Concessions

Distribution service
concessions give the right to use public areas for building distribution lines. The concessions are given by the Chilean Ministry of Energy for an undefined period. Distribution companies have the obligation to serve and connect the customers that
make the requirement in the concession area. The Chilean President can declare a concession expired if the quality of service does not meet certain minimum standards.

Energy Purchases

Since 2005,
with the enactment of the law Ley Corta II, energy sales between generation and distribution companies have been made by an international auction process. After the last modification of the law (Law 20.805  2015), the
auctions of all distribution companies are managed by the CNE. The auctions are based on distribution companies projections of energy demand for the coming years. The result of the process is a pay as bid contract, with an
extension up to 20 years. In addition, the modifications of the law establish a mechanism to supply the excess demand that is not covered by the contract.

Distribution Tariffs to End Customers

Tariffs charged by distribution companies to end customers are determined by the sum of the cost of electricity purchased by the distribution
company, a transmission charge, and the value added from distribution of electricity (VAD), which allows distribution companies to recover their investment and operating costs, including a return on investment which is set by law. The
price for both generation and distribution capacity sold to customers includes a factor which reflects the simultaneous contribution of each customer to peak capacity demand of the system as a whole. The transmission charge reflects the cost paid
for electricity transmission and transformation.

The VAD is based on a so-called efficient model company, which considers the
cost of building and operating the company at the minimum cost, fulfilling quality and safety standards. It includes the annualized investment in distribution assets, the companys operation, administration, and maintenance costs, and an
expected return on investment, before taxes of 10% per year in real terms, based on the replacement cost of assets used for the distribution business.

Generation costs are passed on to distributors end consumers through the Average Node Price stated in governments price
decrees. The Average Node Price is adjusted in three instances: (1) every six months, in May and November of each year, based on local and international indexes; (2) upon the entry of a new supply contract with any distribution company;
and (3) upon indexation of a supply contract in excess of 10%.

Regulatory Charges and Subsidies

The Chilean law deems that transitory subsidies can be granted, if the residential customer tariff increased by 5% or more within a six-month
period. The application of this subsidy is optional and the last one was granted in 2009.

Distribution Tariff-Setting Process

The VAD is set every four years. The CNE classifies companies into groups called Typical Distribution Areas (TDA) based on
economic factors that group companies with similar distribution costs, which in turn determines the equipment requirements of the network. The CNE selects one distribution company for every group and estimates its cost under the concept of an
efficient model company. At the same time, distribution companies also carry out their own studies, which are based on the same one company selected by the CNE for each TDA. The VAD of each TDA is determined in a weighted manner with one third of
the value estimated by the study of the companies and two thirds by the CNE. Preliminary tariffs, as a result of the VAD, are tested to ensure that they provide a rate of return between 6% and 14% on distribution assets.

The real return on investment for a distribution company depends on its actual performance relative to the standards chosen by the CNE for the
efficient model company. The tariff system allows for a greater return to distribution companies that are more efficient than the model company.

##### Table of Contents

Associated Electrical Services

In 2013, the CNE concluded the tariff setting process for 25 regulated associated services (which include meter rental, disconnection and
reconnection of service, among others). These new prices were applied starting March 14, 2014 and will remain in effect until the publication of a new decree, which is expected to occur in November 2016.

Incentives and Penalties

Distribution companies may be required to compensate end customers in the case of electricity shortages that exceed the authorized standards.
These compensatory payments are equal to double the amount of electricity the distribution company failed to provide, using a rate equal to the failure cost.

Regulation in Transmission

The main
transmission system consists of 220 kV or higher voltage lines that are used by generators and customers. Every four years, a study is carried out to evaluate the existing system and to define the expansion plan. On July 31, 2015, the last
study was delivered to the CNE. In February 2016, the Chilean Ministry of Energy promulgated Decree 23T, which defines the current value of the existing lines to be remunerated for the period from 2016 to 2019. The main transmission system is paid
for by generators and customers.

According to the General Electricity Services Law, the transportation of electricity by main
transmission systems and sub-transmission systems are defined as a public service. Therefore, the transmitter has a service obligation and is responsible for the maintenance and improvement of its facilities.

Regulation in Subtransmission

Subtransmission systems are defined as voltage lines exceeding 23 kV. There are six subtransmission systems defined by decree. The
subtransmission systems are paid mainly by customers according to the tariffs fixed by decree of the Chilean Ministry of Energy. Subtransmission tariffs remunerate the Subtransmission Annual Value (VASTx in its Spanish acronym). The
VASTx is estimated every four years in a process carried out by the government. Each subtransmission system develops a study where investment, operation, maintenance, and administration costs are estimated. Investments are economically adapted to
the governments energy projections. Therefore, tariffs only pay for investments in utilized capacity and not for overcapacity. The discount rate established by law is 10%. Operation, maintenance, and administrative costs are estimated under
the efficient model company methodology, as described above. The CNEs consultants examine the studies and develop a report that includes CNE considerations. If major discrepancies are discovered, an expert panel will resolve them
based on technical aspects.

Generators and unregulated customers pay only for the lines they use in each system. In April 2013, Decree
No. 14 was promulgated, which established a tariff schedule for 2011 through 2014.

During 2014, studies were developed to set tolls
for subtransmission systems. The results of these studies should have been applied at the beginning of 2015. However, the authority ruled that the current values will remain in effect for an additional year. Currently, the subtransmission tariff
setting process for 2016-2019 is in its last stage, and will use the CNEs study, which is expected to be completed during 2016.

Environmental
Regulation

The Chilean constitution grants citizens the right to live in a pollution-free environment. It further provides that
certain other constitutional rights may be limited in order to protect the environment. Chile has numerous laws, regulations, decrees and municipal ordinances that address environmental considerations. Among them are regulations relating to waste
disposal (including the discharge of liquid industrial wastes), the establishment of industries in areas that may affect public health, and the protection of water for human consumption.

Environmental Law No. 19,300 was enacted in 1994 and has been amended by several regulations, including the Environmental Impact
Assessment System Rule issued in 1997 and modified in 2001. This law requires companies to conduct an environmental impact study and a declaration of any future generation or transmission projects.

In January 2010, Law No. 19,300 was modified by Law No. 20,417, which introduced changes to the environmental assessment process and
in the public institutions involved, principally creating the Chilean Ministry of Environment and the Superintendence of Environment. Environmental assessment processes are coordinated by this entity and the Environmental

Assessment Service. In June 2011, the Ministry of Environment published Decree 13, emission standards for thermoelectric plants applicable to generation units of at least 50 MW. The objective of
this regulation is to control atmospheric emissions of particulate matter (MP), nitrogen oxides (NOx), sulfur dioxide (SO2) and mercury (Hg), in order to prevent and protect the health of the population and protect the environment. Existing emission
sources are required to meet emission limits as established in the regulation for MP emissions and for SO2 and NOx emissions by June 2015 in highly polluted areas and by June 2016 elsewhere.

In June 2012, Law No. 20,600 created the Environmental Courts, special jurisdictional courts subject to the control of the Chilean
Supreme Court. Their primary function is to resolve environmental disputes within their jurisdiction and look into other matters that are submitted for their attention under the law. The law created three such courts, all of which are in operation.

On December 28, 2012, the Superintendence of Environment was formally created and began to exercise its powers of enforcement and
sanctions pursuant to Chilean environmental regulations.

On September 10, 2014, Law No. 20,780 was enacted and included charges
for the emission of MP, NOx, SO2 and CO2 into the atmosphere. For CO2 emissions, the charge is US$ 5 per emitted ton (not applicable to renewable biomass generation). MP, NOx and SO2
emissions will be charged the equivalent of US$ 0.10 per emitted ton, multiplied by the result of a formula based on the population of the municipality where the generation plant is located and an additional fee of US$ 0.90 per ton of MP
emitted, US$ 0.01 per ton of SO2 emitted and US$ 0.025 per ton of NOx emitted. This tax will be in effect beginning in 2018, taking into account the previous years emissions.

|D. | Property, Plant and Equipment.
|-- | ------------------------------

Our property, plant and equipment are concentrated on
electricity generation and distribution assets in Chile.

Property, Plant and Equipment of Generating Companies

We conduct our generation businesses through Endesa Chile, which owns 28 generation power plants in Chile.

A substantial portion of our generating combined entities cash flow and net income is derived from the sale of electricity produced by
our electricity generation facilities. Significant damage to one or more of our main electricity generation facilities or interruption in the production of electricity, whether as a result of an earthquake, flood, volcanic activity or any other such
cause, could have a material adverse effect on our operations.

Our electricity generation facilities are insured against damage due to
earthquakes, fires, floods, other acts of god (but not for droughts, which are not force majeure risks, and are not covered by insurance) and from damage due to third-party actions, based on the appraised value of the facilities as determined
from time to time by an independent appraiser. Based on geological, hydrological and engineering studies, management believes that the risk of an event with a material adverse effect is remote. Claims under our generating combined entities
insurance policies are subject to customary deductibles and other conditions. We also maintain business interruption insurance providing coverage for the failure of any of our facilities for a period of up to 24 months, including the deductible
period. The insurance coverage taken for our property is approved by each companys management, taking into account the quality of the insurance companies and the needs, conditions and risk evaluations of each generating facility, and is based
on general corporate guidelines. All insurance policies are purchased from reputable international insurers. We continuously monitor and meet with the insurance companies in order to obtain what we believe is the most commercially reasonable
insurance coverage.

Projects under Construction

Los Cóndores Hydroelectric Project

Los Cóndores project will be located in the Maule region, in the San Clemente area. It consists of a 150 MW run-of-the river
hydroelectric power plant, which will use water from the Maule Lagoon reservoir through a 12 km penstock. The power plant will be connected to the SIC at the Ancoa substation (220 kV) through an 87 km transmission line and will
consist of two units.

The basic engineering and the Environmental Impact Statement (DIA in its Spanish acronym) of the
Los Cóndores optimized project were concluded in early 2011. The Environmental Qualifications Resolution (RCA in its Spanish acronym) was obtained in November 2011 and the RCA of the transmission line project was granted
in May 2012. In November 2014, the General Water Authority approved the waterworks permit.

During July 2015, we conducted scale
model tests of the turbines. The results were satisfactory and enabled a hydraulic design, giving rise to the detailed design of the main generating equipment, a process that will take approximately eight months.

During August 2015, Endesa Chile participated in the assembling tests of the Tunnel Boring Machine (TBM), which will be used to
build a 12 km headrace tunnel. By the end of 2015, all components of the TBM were received and assembly was started.

We entered into
easement agreements for 218 structures, or 73.6% of the total structures required for connecting the project to the SIC. In addition, the process of notification and publication of the Electric Definitive Concession began after that the Chilean
Superintendence of Electricity and Fuels issued a Resolution granting the admissibility of the concession presented by Endesa Chile on December 9, 2015.

The main advances in 2015 were:



| |  |  | In January 2015, we completed the first 10 meters of Tunnel Ventana Lo Aguirre.
| | - |  | -------------------------------------------------------------------------------



| |  |  | In April 2015, we completed the digging of the access tunnel to the underground powerhouse (390 meters in length).
| | - |  | ------------------------------------------------------------------------------------------------------------------



| |  |  | In July 2015, we performed the turbines scale model tests.
| | - |  | ----------------------------------------------------------



| |  |  | In August 2015, we completed the digging of the auxiliary tunnel to the discharge tunnel (141 meters in length).
| | - |  | ----------------------------------------------------------------------------------------------------------------



| |  |  | In September 2015, we completed the digging of the discharge tunnel of both units that connect the underground powerhouse with the principal discharge tunnel of the power plant.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In November 2015, we completed the digging of the underground powerhouse.
| | - |  | -------------------------------------------------------------------------



| |  |  | In December 2015, we completed the assembly, outside the tunnel, of the complete shield of the TBM, which initiated the preparations for inserting the TBM into the tunnel. In addition, we completed 70 structural
foundations required for connecting the project to the SIC, with a progress of 13.55% in the construction and 55.8% in the supplies.

Construction is expected to be completed in 2018. This project is being financed primarily with
internally generated funds. The estimated total investment is Ch$ 369,883 million, of which Ch$ 101,795 million was accrued as of December 31, 2015.

Projects Under Development

We
continuously analyze different growth opportunities in Chile. During 2015, our projects portfolio has been modified to permit flexibility in the investment decision. The focus is to have a portfolio with projects that are sustainable from a
technical, environmental, social and economic perspective. Expected dates of commissioning of each of the projects are constantly reviewed and are defined based on commercial opportunities and on our financial capacity to undertake these projects.
The most important projects under development are as follows:

Neltume Hydroelectric Project

The Neltume project is located in Los Ríos region, on the upper part of the Valdivia River basin. The Neltume project consists of a
490 MW installed capacity run-of-the-river hydro power plant. It will be connected to the SIC through a 42 kilometer 220 kV transmission line from Neltume to Pullinque.

In 2007, we started an early process of social integration in the local territory, which has been reinforced through the Indigenous Inquiry
process for the communities in the territory, in order to ascertain their position on the project and comply with Convention No. 169 Indigenous and Tribal Peoples Convention of the International Labor Organization (ILO).
The Indigenous Inquiry process was carried out by Environmental Evaluation Authority (SEA in its Spanish acronym) from the second half of 2013 until the end of December 2015. Due to this process and the engineering studies required, the
Environmental Impact Study was submitted in December 2010.

This Indigenous Inquiry process indicated that there were some social and
environmental controversies in the land associated with the Neltume project. As part of our new strategy of sustainability and community relations, we will develop generation initiatives in a collaborative approach with local communities. The
original Environmental Impact Study was likely to be rejected given the official announcements of various public services issued in late 2015 as well as several meetings with the authorities and in response to the concerns of residents living near
Lake Neltume, we decided to study new design alternatives in order to redesign the discharge to the lake. As a consequence of this decision, we recorded a write-off of Ch$ 2.7 billion in the fourth quarter of fiscal year 2015, associated with
some assets related with the original Environmental Impact Study, which was withdrawn on December 29, 2015, and other studies directly related to the original design. This is not related to the transmission line project, which is continuing as
planned and there are studies underway to be filed again.

Regarding the social area, Endesa Chile has established a permanent working
model for engaging local communities where its power plants and projects are located, supporting forum of discussion and promoting competitive funds in order to be the community and its members themselves who define which projects to develop, based
on their interests and needs.

The new design for the Neltume project will require additional technical and environmental studies, a
process that will be carried out by generating opportunities for collaboration and common views, as far as possible, with communities and local authorities. The purpose of Endesa Chile is to achieve project development in a harmonious way with the
territorial, social and environment framework, in line with the energy requirements of the region and the country.

We expect construction
to start during 2020 and completion in 2025. This project is being financed primarily with internally generated funds. The estimated total investment is between Ch$ 500 and 800 billion, of which Ch$ 43,221 million was accrued as of
December 31, 2015. This accrued amount does not include the aforementioned write-off.

Piruquina Hydroelectric Project

The Piruquina Hydroelectric project is located in Los Lagos region, on Chiloé Island, and will use water from the
Carihueico River. The Piruquina project consists of an 8 MW installed capacity mini hydroelectric power plant. Its architecture provides a small connecting tunnel of approximately 200 meters. It will be connected to the SIC at the Pid-Pid
substation, through a 6 kilometer 23 kV transmission line.

This project has all the engineering studies and principal permits
required, as well as the favorable RCA issued on November 10, 2009 and the Hydraulic Work Permit (PHO in its Spanish acronym) granted on August 6, 2014 that approves and authorizes the construction of hydraulic works for the
power plant.

Currently, we expect construction to start during 2016 and completion in 2018. This project is
being financed primarily with internally generated funds. The estimated total investment is Ch$ 21,141 million, of which Ch$ 2,698 million was accrued as of December 31, 2015.

Ttanti Combined-Cycle Project

The Ttanti project is located in Antofagasta region, on land adjacent to the existing Atacama power plant that is located in the industrial
zone of Mejillones city. The project consists of the construction of three units of natural gas combined-cycle power plant with an aggregate installed capacity of approximately 1.290 MW (430 MW each one) and would be able to use diesel oil as a
backup in case of scarcity of natural gas. The power plant would be connected to SING through a 0.5 km 220 kV double circuit transmission line to the Atacama substation, which will required to be expanded for this purpose.

Currently, the project is in the environment assessment phase. On December 22, 2015, we registered the Addendum No. 1, which
responded to the inquiries formulated by the SEA and we are currently waiting for the new comments that might formulate the SEA.

We
expect to receive the RCA at the end of 2016. If the RCA is favorable, we expect construction to start during 2018 and completion in 2021. The estimated total investment of the first unit is Ch$ 321,653 million, of which
Ch$ 677 million was accrued as of December 31, 2015.

Taltal Combined-Cycle Project

The project consists of the construction of a steam turbine for converting the existing Taltal gas-fired open cycle plant to a combined-cycle
plant by adding a turbine in the vapor phase, which would use the steam generated by the gas turbines heat emissions to produce energy, which will considerably improve its efficiency. The Taltal power plant is located in the Antofagasta
region. Currently, the existing Taltal power plant has two gas turbines of 120 MW each. The extra power to be added by the steam turbine would be approximately 130 MW and therefore, the Taltal power plant would achieve a total capacity of
370 MW and an efficiency increase. The energy produced will be supplied to the SIC through the existing 220 kV double circuit Diego de Almagro  Paposo transmission line.

In December 2013, a DIA was submitted to the SEA for approval, in order to optimize the project. The main modification relates to a change in
the cooling system, which was originally designed as a wet system (using sea water) and is being modified to a dry cooling system (using air condensers). During the second quarter of 2015, Addendum No. 2 was submitted, responding to the second
round of observations formulated by the SEA. During the third quarter of 2015, the SEA formulated its third round of observations and Endesa Chile decided to postpone sending a response until the end of 2016. This decision was made to create
opportunities for dialogue and work in partnership with the local community and thus, build a collaborative, transparent and constructive relationship, enabling us to benefit mutually in the development of the project.

We expect construction to start during 2018 and its commissioning is expected for 2021. This project is being financed primarily with
internally generated funds. The estimated total investment is Ch$ 186,106 million, of which Ch$ 2,879 million was accrued as of December 31, 2015.

Distribution Business

Chilectra

As of
December 31, 2015, Chilectra Chile invested a total of Ch$ 66.5 billion1, among them, the completion of construction works related to the new 220 kV transmission line Chicureo
Substation (approximately Ch$ 2.1 billion) and to 110 kV transmission line Chena  Cerro Navia, specifically construction works in the Substation Cerro Navia  Transelec, in order to begin with the expansion of the Substation. In
addition, construction works related to the 110 kV transmission line Florida  Ochagavía, which will be used as support of both stretches Tap Club Hipico  San Joaquin (Ch$ 745.4 million), 110 kV transmission line
Chena  Espejo (approximately Ch$ 54.1 million), and the construction works related to the 110 kV transmission line Florida  Los Almendros (Ch$ 208.9 million), in which some towers were transferred to the area of
Quebrada de Macul Hondonada. Regarding the medium voltage network, five new feeders were built: 12 kV feeder Einstein of the Substation Recoleta (Ch$ 383.1 million), 12 kV feeder Los Cerezos of the Substation Macúl
(approximately Ch$ 424.5 million), 12 kV feeder Tegualda of the Substation Santa Elena (approximately Ch$ 844.9 million), 12 kV feeder Necochea of the Substation San José (approximately Ch$ 325.5 million) and the
12 kV feeder Antuco of the Substation Santa Raquel (approximately Ch$ 165.1 million).

Regarding the large customers supply, the following feeders entered into operation: 23 kV
feeders Luna 2 and Luna 3 (23 kV) of the Substation Chacabuco, which serves Google (approximately Ch$ 274.8 million), 12 kV feeders Visviri and Helsby (12 kV) of the Substation Andes, which serves Mall Plaza Los Domínicos
(approximately Ch$ 522.9 million), 12 kV feeder Santa Clara of the Substation Recoleta, which serves Claro and Citypark (Ch$ 299.5 million). Finally, three feeders are currently in construction and they are expected to enter into
operation during 2016.

Major Encumbrances

As of December 31, 2015, we have full ownership of our assets and they are not subject to material encumbrances.

Climate Change

In recent years, Chile
and the region have seen an increase of developments related to NCRE and strategies to combat climate change. This has required both the public and private sectors to adopt strategies in order to comply with the new environmental requirements, as
evidenced by legal obligations at the local level, commitments assumed by countries at the international level, and the demanding requirements of the international markets.

NCREs provide energy with minimal environmental impact and without CO2 emissions. They
are therefore considered technological options that strengthen sustainable energy development as they supplement the production of traditional generators.

The Canela I wind farm (18 MW, in operation since 2007) and Canela II wind farm (60 MW, in operation since 2009) are the
NCRE facilities owned by Endesa Chile, which have contributed clean and renewable energy to the SIC. Regarding the development of CO2 emission reduction mechanisms, the projects in the Clean
Development Mechanism (CDM) circuit were as follows:

Canela I Wind Farm: On April 3, 2009, the United
Nations Framework Convention on Climate Change (UNFCCC) approved the registration of the Canela project as a CDM project, which recognizes that this wind farm may verify and trade credits for greenhouse gas emissions that it will avoid
during its useful life. On February 24, 2014, the UNFCCC approved the issuance of credits for 44,919 tons of CO2 emissions for the operational period of 2009 through 2011. Certified
Emission Reductions (CERs) of subsequent periods have not yet been verified.

On August 8, 2013, the Canela I wind farm
achieved registration under the Gold Standard (GS). This allowed Endesa Chile to apply for the GS verification process, which would provide GS Voluntary Emission Reductions (VER).

Canela II Wind Farm: On August 12, 2012, the UNFCCC approved the registration of the Canela II project as a CDM project, which
recognizes that this wind farm may verify and trade the greenhouse gas emissions that it will avoid during its useful life.

In compliance with the group climate change guidelines,
we have secured the certification of our carbon footprint for a fourth time. The Spanish Association of Standards and Certification (Asociación Española de Normalización y Certificación or AENOR), an
independent certification authority, acknowledged the validity of the methodology. Acknowledgement by AENOR includes verification of the groups carbon footprint reports from 2009 to 2014. A carbon footprint is the sum of all greenhouse gases
(GHGs) produced by a company in the course of its business activity. We are striving to reduce our emissions as part of our commitment to combat climate change. The first step involves measuring our carbon footprint.

As part of the process of calculating our carbon footprint, we plan to obtain a GHG inventory, including direct emissions associated with
activities controlled by us. We also plan to obtain a GHG inventory of indirect emissions, which are not generated through sources we control but are consequences of our activities.

The tools used to calculate emissions include audits and checks at all of our facilities. This enables us to monitor our carbon footprint
throughout the entire electricity supply chain. Calculating the carbon footprint also enables us to identify phases of our activities with the greatest potential to boost energy efficiency and reduce emissions.

|1. | Discussion of Main Factors Affecting Operating Results and Financial Condition of the Company
|-- | ---------------------------------------------------------------------------------------------

We own and operate electricity generation and distribution companies in Chile. Our revenues, income and cash flows come from the operations of
the combined entities and associates in Chile.

Factors such as (i) hydrological conditions, (ii) fuel prices,
(iii) regulatory developments, (iv) exceptional actions adopted by governmental authorities and (v) changes in the economic conditions may materially affect our financial results. In addition, our results from operations and financial
condition are affected by variations in the exchange rate between the Chilean peso and the U.S. dollar. We have certain critical accounting policies that affect our combined operating results. The impact of these factors on us, for the years covered
by this Report, is discussed below.

Since May 2014, we have fully combined GasAtacama Holding and its subsidiaries, including GasAtacama,
in our combined financial statements, as a result of Endesa Chiles purchase of an additional 50% of GasAtacama Holdings shares from Southern Cross Latin America Private Equity Fund III, L.P., which increased our economic interest in
GasAtacama to 60.7% and granted the control of this entity. Prior to this transaction, the company was recognized as jointly-controlled company.



|a. | Generation Business
|-- | -------------------

A substantial part of our generation capacity depends on the
prevailing hydrological conditions. Our installed capacity as of December 31, 2015 and 2014 was 6,351 MW and as of December 31, 2013 was 5,571 MW, of which 54.6% and 62.2% respectively, was hydroelectric. The 780 MW increase in
installed capacity between December 31, 2013 and 2014 is due to the inclusion of GasAtacamas thermal generation capacity since May, 2014. See Item 4. Information on the Company  D. Property, Plant and
Equipment.

Hydroelectric generation was 11,842 GWh, 11,561 GWh and 9,889 GWh in 2015, 2014 and 2013, respectively. Our 2015
hydroelectric generation was higher than 2014 mainly due to more favorable hydrological conditions. Nevertheless, some important reservoirs are still at low levels due to several years of drought since 2010, characterized by low rainfalls and a poor
snowmelt.

Hydrological conditions in Chile can range from very wet, as a result of several years of abundant rainfall and lakes at their
peak capacity, to extremely dry, as a consequence of prolonged droughts lasting for several years, the partial or material depletion of water reservoirs and the significant reduction of snow and ice in the mountains, which in turn leads to
materially lower levels of hydrology as a consequence of lower melts. In between these two extremes, there is a wide range of possible hydrological conditions. For instance, a new year of drought has very different impacts on our business, depending
on whether it follows several years of drought or a period of abundant rainfall. On the other hand, a good hydrological year has less marginal impact if it comes after several wet years than after a prolonged drought. In Chile, the months that
typically have the most precipitation are May through August, and the months when snow and ice melts typically are October though March, providing water flow to our lakes, reservoirs and rivers, which supply our hydroelectric plants, most of them
concentrated in southern Chile. For purposes of discussing the impact of hydrological conditions on our business, we generally categorize our hydrological conditions into dry, wet or normal, although there are many other possible scenarios well
beyond these three. Extreme hydrological conditions materially affect our operating results and financial conditions. However, it is difficult to indicate the effects of hydrology on our operating income, without concurrently taking into account
other factors, because our operating income can only be explained by looking at a combination of factors and not each one on a stand-alone basis.

Hydrological conditions affect electricity market prices, generation costs, spot prices, tariffs and the mix of hydroelectric or thermal
generation, which is constantly being defined by the CDEC to minimize the operating cost of the entire system. Pass-through hydroelectric generation is almost always the least expensive method to generate electricity and normally has a marginal cost
close to zero. In the case of reservoirs, Chilean authorities assign a cost for the use of water, which may lead to hydroelectric generation not necessarily being the lowest marginal cost. This is the case of Laja Lake, which is used as a reference
for the SIC. The cost of thermal generation does not depend on hydrological conditions but instead on international commodity prices for LNG, coal, diesel and fuel oil.

Spot prices primarily depend on hydrological conditions and commodity prices. Under most circumstances, abundant hydrological conditions lower
spot prices while dry conditions normally increase prices. Spot market prices affect our results since we purchase electricity in the spot market in the case that we have deficits between our contracted energy sales and our generation, and we sell
electricity in the spot market if we have electricity surpluses.

There are many other factors that may affect operating income, including
the level of contracted sales, purchases/sales in the spot electricity market, commodity prices, energy demand, technical and unforeseen problems that can affect the availability of our thermal plants, plant locations in relation to urban demand
centers, and transmission system conditions, among others.

##### Table of Contents

To illustrate the effects of hydrology on our operating results, the following table describes
certain hydrological conditions, their expected effects on spot prices and generation, and the expected impact on our operating income, assuming that other factors remain unchanged. In all cases, hydrological conditions do not have an isolated
effect but need to be evaluated in conjunction with other factors to better understand the impact on our operating results.

If factors other than those described above apply, the expected impact of hydrological conditions on operating
results will be different than those shown above. For example, in a dry year with lower commodity prices, spot prices may decrease, or in a wet year if the demand grows, or generation plants are not available for technical or other reasons, the spot
price may increase, altering the impact of hydrological conditions discussed in the table above.

In recent years, additional thermal
capacity has helped to offset poor hydrological conditions, resulting in better operating margins. However, operations of the Bocamina I and II thermal power plants were stopped for extended periods in 2014 due to an injunction from the Court of
Concepción. This shutdown would have had less impact if there had been better hydrological conditions during this period. On July 1, 2015, the plants became available for dispatch after obtaining the required authorization.

Hydrological conditions were less favorable than the historical average during the period between January 2015 and July 2015. During this
time, we also had reduced thermal generation due to the shutdown of Bocamina I and II, and higher spot prices than normal years that to some extent were mitigated by the reduction of commodity prices. Our generation was lower than our contracted
sales, resulting in higher energy purchase costs. Since July 2015, Bocamina I and II have been available and since August 2015 hydrological conditions have improved, and have been within the normal historical range, resulting in better operating
income compared to the same period in 2014.

Hydrological conditions in 2013 were slightly drier than 2014, with fuel oil and coal being
more expensive in 2013 than in 2014. We also purchased energy on the spot market at a higher price to meet our contractual obligations. Operating income, excluding depreciation, amortization and impairment losses, was similar to 2014.

|b. | Distribution Business
|-- | ---------------------

Our electricity distribution business is conducted through
Chilectra Chile. For the year ended December 31, 2015, electricity sales amounted to 15,893 GWh, an increase of 1.3% compared to 2014. For the year ended December 31, 2014, electricity sales totaled 15,690 GWh, increasing by 3.6% compared to
2013. Chilectra Chile operates in the Santiago metropolitan area, providing electricity to almost 1.8 million customers. Santiago is the countrys most densely populated area and has the highest concentration of industries, industrial
parks and office facilities in the country. Chilectra Chile faces growing electricity demand, because of organic growth in demand, which obliges it to continually invest in its facilities.

Among the key factors that impact our financial in the distribution business results are regulations. This is especially true when the actions
adopted by government authorities define or intervene with directly regulated customer tariffs, or affect the price at which distributors can buy their energy. Our ability to buy electricity relies highly on generation availability, and to
regulation in a lesser degree. In the past, we focused on reducing physical losses, especially those due to illegally tapped energy, currently at a 5.3% level. We are working on improving our collectability indices and our efficiency.



|c. | Selective Regulatory Developments
|-- | ---------------------------------

The regulatory framework governing our businesses
has a material effect on our operating results. In particular, regulators set (i) energy prices in the generation business, taking into consideration factors such as fuel costs, reservoir levels, exchange rates, future investments in installed
capacity and demand growth, and (ii) distribution tariffs taking into account the costs of energy purchases paid by distribution companies (which distribution companies pass on to their customers) and the Value Added from
Distribution, or VAD, all of which are intended to reflect investment and operating costs incurred by distribution and generation companies and to allow our companies to earn a regulated level of return on their investments and guarantee
service quality and reliability. Our earnings are determined to a large degree by government regulators, mainly through the tariff setting process.

Chilectra Chiles tariffs will be reviewed during the second half of 2016. Such reviews seek to capture distribution efficiency and
economies of scale based on economic growth.

For additional information relating to the regulatory framework, see Item 4.
Information on the Company  B. Business Overview  Electricity Industry Regulatory Framework.



|d. | Economic Conditions
|-- | -------------------

Macroeconomic conditions, such as changes in employment levels and
inflation or deflation may have a significant effect on our operating results. Macroeconomic factors, such as the variation of the Chilean peso against the U.S. dollar may impact our operating results, as well as our assets and liabilities,
depending on the amounts denominated in U.S. dollars. For example, a devaluation of the Chilean peso against the U.S. dollar increases the cost of capital expenditure plans. For additional information, see Item 3. Key
Information  D. Risk Factors  Foreign exchange risks may adversely affect our results and the U.S. dollar value of dividends payable to ADS holders and  Chilean economic fluctuations could affect our results of
operations and financial condition as well as the value of our securities.

Local Currency Exchange Rate

Variations in the parity of the U.S. dollar and the Chilean peso may have an impact on our operating results and overall financial position.
The impact will depend on the level at which tariffs are pegged to the U.S. dollar, U.S. dollar-denominated assets and liabilities.

The
following table sets forth the closing and average Chilean pesos per U.S. dollar exchange rates for the years indicated:

|e. | Critical Accounting Policies
|-- | ----------------------------

Critical accounting policies are defined as those that
reflect significant judgments and uncertainties which would potentially result in materially different results under different assumptions and conditions. We believe that our most critical accounting policies with reference to the preparation of our
combined financial statements under IFRS are those described below.

For further detail of the accounting policies and the methods used in
the preparation of the combined financial statements, see Notes 2 and 3 of the Notes to our combined financial statements

Impairment of Long-Lived
Assets

During the year, and principally at year end, we evaluate whether there is any indication that an asset has been impaired.
Should any such indication exist, we estimate the recoverable amount of that asset to determine, where appropriate, the amount of impairment. In the case of identifiable assets that do not generate cash flows independently, we estimate the
recoverability of the cash generating unit to which the asset belongs, which is understood to be the smallest identifiable group of assets that generates independent cash inflows.

Notwithstanding the preceding paragraph, in the case of cash generating units to which goodwill or intangible assets with an indefinite useful
life have been allocated, a recoverability analysis is performed routinely at each period end.

The recoverable amount is the greater of
(i) the fair value less the cost needed to sell and (ii) the value in use, which is defined as the present value of the estimated future cash flows. In order to calculate the recoverable value of property, plant and equipment, goodwill and
intangible assets, that form part of a cash generating unit, we use value in use criteria in nearly all cases.

To estimate the value in
use, we prepare future pre-tax cash flow projections based on the most recent budgets available. These budgets incorporate managements best estimates of cash generating units, revenues and costs using sector projections, past experience and
future expectations.

In general, these projections cover the next five years, estimating cash flows for subsequent years by applying
reasonable growth rates, between 4.5% and 5.1%, which are not increasing nor do they exceed the average long-term growth rates for the particular sector.

These cash flows are discounted at a given pre-tax rate in order to calculate their present value. This rate reflects the cost of capital of
the business in Chile. The discount rate is calculated taking into account the current time value of money and the risk premiums generally used by market participants for the specific business activity.

The pre-tax nominal discount rates applied in 2015, 2014 and 2013 are as follows:



|        |  |              |  |                         |     |   |         |  |      |         |  |  |         |   |  |         |      |   |         |  |     |   |  |  |      |  
|------- |  | ------------ |  | ----------------------- | --- | - | ------- |  | ---- | ------- |  |  | ------- | - |  | ------- | ---- | - | ------- |  | --- | - |  |  | ---- | -
|        |  |              |  |                         |    
|        |  |              |  | Year ended December 31, |    
|        |  |              |  | 2015                    |     |   | 2014    |  |      | 2013    | 
|Country |  | Currency     |  | Minimum                 |     |   | Maximum |  |      | Minimum |  |  | Maximum |   |  | Minimum |      |   | Maximum | 
|Chile   |  | Chilean peso |  |                         | 8.1 | % |         |  | 12.7 | %       |  |  | 7.9     | % |  |         | 13.0 | % |         |  | 7.8 | % |  |  | 16.3 | %

If the recoverable amount is less than the net carrying amount of the cash generating unit, the corresponding
impairment loss provision is recognized for the difference, and charged to Reversal of impairment loss (impairment loss) recognized in profit or loss in the combined statement of comprehensive income.

Impairment losses recognized for an asset in prior periods are reversed when its estimated recoverable amount changes, increasing the
assets value with a credit to earnings, limited to the assets carrying amount if no adjustment had occurred. In the case of goodwill, any adjustments made are not reversible.

Litigation and Contingencies

We are currently involved in certain legal and tax proceedings. As discussed in Note 24 of the Notes to our combined financial statements as
of December 31, 2015, we have estimated the probable outflows of resources for resolving these claims to be Ch$ 14.8 billion. We have reached this estimate after consulting our legal and tax advisors who are carrying out our defense
in these matters and an analysis of potential results, assuming a combination of litigation and settlement strategies.

Hedge Cash
Revenues Directly Linked to the U.S. Dollar

We have established a policy to hedge the portion of our revenues directly
linked to the U.S. dollar by obtaining financing in U.S. dollars. Exchange differences related to this debt, as they are cash flow hedge transactions, are charged net of taxes to an equity reserve account that forms part of Other Comprehensive
Income and recorded as income during the period in which the hedged cash flows are realized. This term has been estimated at ten years.

This policy reflects a detailed analysis of our future U.S. dollar revenue streams. Such analysis may change in the future due to new
electricity regulations limiting the amount of cash flows tied to the U.S. dollar.

Pension and Post-Employment Benefit Liabilities

We have various defined benefit plans for our employees. These plans pay benefits to employees at retirement and use formulas
based on years of service and employee compensations. We also offer certain additional benefits for some retired employees in particular.

The liabilities shown for the pensions and post-employment benefits reflect our best estimate of the future cost of meeting our obligations
under these plans. The accounting applied to these defined benefit plans involves actuarial calculations which contain key assumptions that include employee turnover, life expectancy, retirement age, discount rates, the future level of employee
compensations and benefits, the claims rate under medical plans and future medical costs. These assumptions change as economic and market conditions vary and any change in any of these assumptions could have a material effect on the reported results
from operations.

The effect of an increase of 100 basis points in the discount rate used to determine the present value of the
post-employment defined benefits would decrease the liability by Ch$ 4.1 billion, Ch$ 3.9 billion and Ch$ 3.2 billion as of December 31, 2015, 2014 and 2013, respectively, and the effect of a decrease of 100 basis points in the
rate used to determine the present value of the post-employment defined benefits would increase the liability by Ch$ 4.7 billion, Ch$ 4.6 billion and Ch$ 3.7 billion as of December 31, 2015, 2014 and 2013, respectively.

Distribution Business

Distribution revenues are mainly derived from the resale of electricity purchased from generators. Revenues associated with distribution
include the recovery of the cost of electricity purchased and the resulting revenue from the VAD, which is associated with the recovery of costs and the return on the investment with respect to the distribution assets, plus the physical energy
losses permitted by the regulator. Other revenues derived from our distribution business consist of charges for new connections and the maintenance and rental of meters, among others.

Generation Business: Revenues

Revenues from Endesa Chile increased by Ch$ 323.2 billion, or 26.5% in 2015, compared to 2014, mainly due to
(i) Ch$153.6 billion as a result of 16.0% increase in average energy sale prices, (ii) Ch$ 88.9 billion as result of increased physical sales of 2,401 GWh, or 11.3%, due to both increased contractual sales, especially to
distributors, and increased sales in the spot market, and (iii) Ch$ 69.9 billion of higher revenues contributed by GasAtacama, a combined entity since May 2014.

Distribution Business: Revenues

Revenues from Chilectra Chile increased by Ch$ 129.8 billion, or 11.5%, in 2015 compared to 2014. This increase is a result of
(i) higher energy sales of Ch$ 115.1 billion, mainly due to Ch$ 7.1/MWh (10.7%) increase of the tariff to regulated clients due to regular indexed cost adjustment in the tariff, which accounted for Ch$ 105.4 billion of the increase
and (ii) Ch$ 16.4 billion higher revenues from other services, mainly related to tolls charged to generating companies and rental and maintenance of street lighting and network installments. The number of customers rose by
approximately 43,500 in 2015 compared to 2014, totaling approximately 1,780,800.

Combined Operating Costs

Total operating costs consist primarily of energy purchases from third parties, fuel purchases, tolls paid to transmission companies,
depreciation, amortization and impairment losses, maintenance costs, employee salaries and administrative and selling expenses.

Generation Business: Operating Costs

Operating costs increased by Ch$ 130.7 billion, or 17.4%, in 2015 compared to 2014, mainly due to (i) Ch$ 39.5 billion of
higher other variable procurement and services costs mostly attributable to (a) Ch$ 23.7 billion related to the cost of the agreement with Geners Nueva Renca combined-cycle power plant that allows Endesa Chile to use its available LNG and
(b) Ch$ 9.4 billion of higher water transportation costs for the operation of the San Isidro power plant, (ii) Ch$ 36.9 billion of higher gas transportation costs related to additional energy purchases,
(iii) Ch$ 22.0 billion of higher fuel consumption costs mainly due to Endesa Chiles higher coal consumption costs of Ch$ 16.0 billion, and (iv) increased purchases of energy on the spot market of Ch$ 32.2 billion
due to higher sales.

Distribution Business: Operating Costs

Operating costs of Chilectra Chile increased by Ch$ 128.0 billion, or 15.0%, in 2015 compared to 2014, mainly due to Ch$ 115.3 billion
greater energy purchases, primarily attributable to a higher average purchase price of Ch$ 6.5 /GWh (13.2%) as a result of regular indexed costs adjustment that accounted for Ch$ 105.3 billion. In addition, operating costs increased because of
variable procurement and service costs of Ch$ 8.2 billion, and higher transportation costs of Ch$ 4.5 billion.

Selling and administrative expenses increased by Ch$ 34.6 billion, or 9.7%, in 2015 compared to 2014, mainly
due to (i) higher other fixed costs of Ch$ 24.9 billion mostly attributable to increased costs related to the corporate reorganization and higher fines for sanctions and litigations, and (ii) higher charges in Endesa Chile for depreciation
of Ch$ 2.8 billion from the full consolidation of GasAtacama.

Financial Results

The net financial results for the year ended December 31, 2015 was an expense of Ch$ 97.9 billion, an increase of
Ch$ 30.8 billion, or 46.0%, compared to 2014. This increase was primarily due to (i) higher charges for foreign currency exchange differences of Ch$ 29.8 billion mainly as a result of the devaluation of the Chilean peso against
the U.S. dollar that affected the valuation of financial debt and derivative instruments and (ii) decreased gain for indexed assets and liabilities of Ch$ 10.4 billion due to lower inflation rate in 2015, compared to 2014. These greater
expenses were partially offset by Ch$ 8.9 billion of lower financial costs due to lower intercompany debt.

Others

The gain from sales of assets for the year ended December 31, 2015 was Ch$ 20.1 billion, a decrease of Ch$ 50.8 billion or
71.7%, compared to 2014. This decrease was primary due non-recurring gains in 2014 of (i) Ch$ 42.6 billion recorded in 2014 arising from the revaluation of the 50% pre-existing investment in GasAtacama and a recognition of its accumulated
currency exchange differences and (ii) Ch$ 21.1 billion recorded in 2014 from the sale of the equity interest in Los Maitenes and Aguas Santiago Poniente (ENEA Project). The decrease was partially offset by a net gain of Ch$ 14.6
billion from the sale of land (Alonso de Córdova substation) during the fourth quarter of 2015.

Our share of the profit (loss) of
associates and joint ventures investments accounted for using the equity method in 2015 was Ch$ 8.9 billion, an increase of Ch$ 63.3 billion as compared to 2014, primarily due to the non-recurring impairment loss of Ch$ 69.1 billion
recorded in December 2014 in connection with HidroAysén project. This decision was based on the uncertainty of recovering the investment made in the project, mainly as a consequence of the long judicial process in order to obtain
environmental approvals.

Combined Income Tax Expenses

Combined income tax expenses totaled Ch$ 109.7 billion in 2015, a decrease of Ch$ 23.1 billion, or 17.4%, compared to
2014. The decrease in corporate income tax expense was mainly due to the absence in 2015 of a one-time effect recorded as a net deferred tax liability of Ch$ 66.7 billion in 2014, following the tax reform enacted in Chile on September 29, 2014.
The 2014 tax reform established a gradual increase in the taxation rate until 2018 and is expected to slightly affect our results in the future, considering that the main impacts on deferred taxes have been already recognized.

The combined effective tax rate was 24.0% in 2015 and 39.9% in 2014.

The increase in net income attributable to non-controlling interests of Ch$ 58.0 billion in 2015 compared to
2014, is primarily due to the Ch$ 69.3 billion increase of net income attributable to the non-controlling interests of Endesa Chile for 2015, which in turn is mainly due to the increase in net income in Endesa Chile by Ch$ 154.7 billion.
The controlling and economic interest in Endesa Chile is the same in both years (59.98%).

Generation Business: Revenues

Revenues increased by Ch$ 260.8 billion, or 27.2%, in 2014 compared to 2013, mainly due to (i) Ch$ 160 billion as result of 29.5%
increase in average energy sales prices; (ii) Ch$ 113.0 billion of revenues contributed by GasAtacama, which is consolidated by Endesa Chile since May 2014, and (iii) Ch$ 30 billion as a consequence of an increase in physical
sales of 3.7% mainly to distribution companies. This increase was partially offset by Ch$ 39.7 billion lower revenues from other services, mostly tolls.

Distribution Business: Revenues

Revenues from our Chilectra Chile combined entity increased by Ch$ 152.9 billion, or 15.7%, in 2014 compared to 2013, as a result of
(i) higher average energy prices due to indexed cost adjustments not previously reflected that contributed higher revenues by Ch$ 124.5 billion and (ii) Ch$ 30.6 billion due to 550 GWh, or 3.6%, higher physical sales due to lower
temperatures than the previous year. The number of customers rose by approximately 43,400 in 2014 compared to 2013, totaling approximately 1,737,300.

Combined Operating Costs

Combined
operating costs consist primarily of energy purchases from third parties, fuel purchases, depreciation, amortization and impairment losses, maintenance costs, tolls paid to transmission companies, employee salaries and administrative and selling
expenses.

Generation Business: Operating Costs

Operating costs of Endesa Chile increased by Ch$ 255.3 billion, or 51.6%, in 2014 compared to 2013, mainly due to (i) Ch$ 164.0
billion increased purchases of energy on the spot market , primarily due to the stoppage of the Bocamina II thermal power plant from December 2013 through 2014 and (ii) Ch$ 93.9 billion higher fuel consumption costs mainly as a consequence
of the full combination of GasAtacama since May 2014, which increased costs by Ch$ 53.9 billion and a Ch$ 35.0 billion increase associated with the San Isidro and Tarapaca thermal plants due to higher price of LNG.

Distribution Business: Operating Costs

Operating costs of Chilectra Chile increased by Ch$ 143.3 billion, or 20.1%, in 2014 compared to 2013, mainly due to greater energy
purchases of Ch$ 137.9 billion to cover the physical energy sales, of which Ch$ 111.4 billion was the result of higher average purchase price of Ch$ 6.9/GWh due to the regular indexation cost adjustments and Ch$ 26.5 billion by 589
GWh of higher physical energy purchases.

Selling and administrative expenses increased by Ch$ 9.4 billion, or 2.7%, in 2014 compared to 2013, mainly
due to higher charges for depreciation and an impairment of Ch$ 21.2 billion in the generation business, which includes Ch$ 12.6 billion of impairment losses with respect to the Punta Alcalde project. On January 29, 2015,
Endesa Chile halted development of the power plant and the related transmission project in light of the changes requested by a Chilean court, which may require major modifications to make the project economically and technologically more
sustainable. This was offset by Ch$ 7.2 billion lower depreciation and impairment losses in Chilectra Chile.

Financial Results

The net financial results for 2014 was a net expense of Ch$ 67.0 billion. The net expense increased Ch$ 10.7 billion, or 19.0%,
compared to 2013. This increase is mainly due to: (i) increased charges for foreign currency exchange differences of Ch$ 19.6 billion, as a result of the devaluation of the Chilean peso against the U.S. dollar that affected the valuation
of derivative instruments and (ii) higher financial costs by Ch$ 5.9 billion, mainly due to the increase in the financial debt. This increase was partially offset by a gain for indexation adjustments of Ch$ 13.7 billion mainly
due to the positive variation of financial derivatives asset position over the UF.

Others

Gains from sales of assets increased by Ch$ 56.4 billion, mainly due to the recognition of a Ch$ 42.5 billion gain arising from
the revaluation of the 50% pre-existing investment participation in GasAtacama and the recognition of its accumulated currency exchange differences, and a Ch$ 21.1 billion gain on the sale of Los Maitenes and Aguas Santiago Poniente (Enea
Project in former Manso de Velasco), partially offset by reduced sales of investment properties and transmission lines of Ch$ 11.0 billion. The share of profits (loss) of associates and joint ventures accounted for using the equity method
decreased by Ch$ 78.7 billion, mainly as a result of the impairment loss of Ch$ 69.1 billion in connection with the HidroAysén project, due to Endesa Chiles decision not to proceed with this project. This decision was based on the
uncertainty of recovering the investment made in the project, mainly as a consequence of the long judicial process in order to obtain environmental approvals. This result also decreased by Ch$13.9 billion as a result of combination of GasAtacama
Holding beginning in 2014 and not being accounted under the equity method as it was during the 2013. Such decreases were partially offset by an increase of Ch$ 4.4 billion relating to Electrogas.

As a result of all the foregoing, total non-operating results for 2014 amounted to a net expense of Ch$ 50.5 billion.

Combined Income Taxes

Combined income tax increased by Ch$ 71.0 billion in 2014 compared to 2013 mainly due to (i) increased charges of
Ch$ 62.0 billion due to the one-time recognition effect of net deferred tax liabilities as a result of the application of the tax reform enacted in Chile on September 29, 2014, which established a gradual increase in the taxation rate
and, (ii) the additional net income due to the combination of GasAtacama that resulted in additional income tax by Ch$ 10.2 billion.

The effective tax rate was 39.9% in 2014 and 16.5% in 2013.

The net income attributable to non-controlling interests decreased by Ch$ 45.8 billion in 2014 compared to
2013 primarily due to the Ch$ 46.9 billion of lower net income attributable to the non-controlling interests of Endesa Chile for the corresponding years, which in turn is mainly due to the decrease in the net income contributed by Endesa Chile of
Ch$ 117 billion. The controlling and economic interest in Endesa Chile remained the same in both periods (59.98%).

|B. | Liquidity and Capital Resources.
|-- | --------------------------------

We have no significant assets other than the stock of
our Chilean combined entities. The following discussion of cash sources and uses reflects the key drivers of our cash flow.

We have a
direct ownership in Endesa Chile (60.0%) and Chilectra Chile (99.1%), our main combined entities. We, on a stand-alone basis, receive cash inflows from our Chilean combined entities, as well as from related companies in Chile. Cash flows of our
associates may not be available to satisfy our own liquidity needs, mainly because they are not wholly-owned, and because there is a time lag before we have effective access to those funds through dividends or capital reductions. However, we believe
that cash flow generated from our business operations, as well as cash balances, borrowings from commercial banks, and ample access to both Chilean and foreign capital markets will be sufficient to satisfy all our needs for working capital, expected
debt service, dividends and planned capital expenditures in the foreseeable future.

Set forth below is a summary of our combined cash
flow information for the years ended December 31, 2015, 2014 and 2013:

For the year ended December 31, 2015, net cash flow from operating activities was
Ch$ 576 billion, an increase of Ch$ 311.6 billion, or 117.6%, compared to Ch$ 265 billion for the same period in 2014. The increase was primarily the result of an increase in collections from the sale of goods and services of
Ch$ 662 billion comprised of: (i) Ch$ 286 billion from Endesa Chile, on a stand-alone basis, mainly due to an increase in physical sales, (ii) Ch$ 116 billion from the full inclusion of GasAtacama and (iii) Ch$ 337
billion from Chilectra Chile due to an increase of the tariff for regulated customers, despite the slight decrease in the collection rate from 99.6% to 97.0% in 2015 compared to 2014. These factors were due to increasing economic activity in recent
years and greater per capita consumption. This increase was partially offset by: (i) an increase in payments to suppliers of goods and services of Ch$ 194 billion comprised of Ch$ 151 billion from Endesa Chile, which was mostly a
consequence of higher variable procurement and service costs of Ch$ 39.5 billion, mostly attributable to costs related to the Endesa Chiles lease of Geners Nueva Renca combined-cycle power plant for use of Endesa Chiles available
LNG, Ch$ 36.9 billion higher transportation costs related to additional energy purchases, and also comprised of Ch$ 133 billion from Chilectra Chile mainly due to Ch$ 115.3 billion of higher energy purchases due to the higher periodic price
index changes; (ii) an increase in income tax payments of Ch$ 100 billion mainly due to lower tax refunds for Endesa Chile and increased tax advances for Chilectra Chile as a consequence of higher sales and (iii) an increase in
other payments for operating activities of Ch$ 33 billion attributable to higher VAT payments by Chilectra Chile and GasAtacama as a consequence of higher sales (see Item 5. Operating and Financial Review and Prospects  A.
Operating Results. 2. Analysis of Results of Operations for the Years Ended December 31, 2015 and 2014).

##### Table of Contents

For the year ended December 31, 2014, net cash flow from operating activities was
Ch$ 265 billion, a decrease of Ch$ 178 billion, or 40.2%, compared to net cash flow from operating activities of Ch$ 443 billion for 2013. The decrease was primarily the result of an increase in payments to suppliers of
goods and services of Ch$ 392 billion comprised of Ch$ 283 billion from Chilectra Chile, mainly due to Ch$ 137.9 billion greater energy purchases to cover physical energy sales and Ch$ 228 billion from Endesa Chile as a result of
Ch$ 164.0 billion greater purchases of energy on the spot market as a consequence of the shutdown of the Bocamina II coal-fired plant during 2014, as well as Ch$ 93.9 billion of higher fuel consumption in connection with the full inclusion of
GasAtacama since May 2014 and higher LNG prices in comparison to 2013. In addition, lower operating cash flow was attributable to a decrease in the collections from insurance policies and services, annual payments, and other benefits from policies
held in 2014 of Ch$ 74 billion compared to 2013. In 2013, Endesa Chile received a Ch$ 72.2 billion insurance reimbursement for the loss of profits from the Bocamina I power plant and Ch$ 1.4 billion of material damages at the Bocamina II
power plant, both related to the 2010 earthquake in Chile. The decrease in 2014 was partially offset by (i) the increase in collections from the sale of goods and services of Ch$ 282 billion comprised of Ch$ 171 billion from Endesa
Chile, on a stand-alone basis, mainly due to higher physical sales, Ch$ 122 billion from the full inclusion of GasAtacama and Ch$ 71 billion from Chilectra Chile due to greater average energy sales even when the collection rate remained stable in
comparison with 2013 (99.6% in 2014 versus 99.9% in 2013), and (ii) a decrease in income tax payments of Ch$ 34 billion mainly attributable to higher tax refunds in Endesa Chile (see Item 5. Operating and Financial Review
and Prospects  A. Operating Results. 3. Analysis of Results of Operations for the Years Ended December 31, 2014 and 2013).

For the year ended December 31, 2015, net cash used in investing activities was Ch$ 297 billion, compared to net cash used in
investing activities of Ch$ 189 billion for the same period of 2014. The increase was mainly due to the acquisition of fixed assets totaling Ch$ 310 billion (see Item 4. Information on the Company  A. History and
Development of the Company  Investment, Capital Expenditures and Divestitures), all of which were partially offset by proceeds from dividends classified as investment cash flow of Ch$ 10 billion, loss of control of combined
entities for Ch$ 7 billion, arising from the proceeds received for the sale of all of our shareholdings in Sociedad Concesionaria Túnel El Melon S.A., and interest received of Ch$ 3 billion.

For the year ended December 31, 2014, net cash used in investing activities was Ch$ 189 billion, compared to net cash used in
investing activities of Ch$ 106 billion for 2013. The increase was mostly due to the acquisition of fixed assets totaling Ch$ 197 billion (see Item 4. Information on the Company  A. History and Development of the
Company  Investment, Capital Expenditures and Divestitures), the inclusion of GasAtacama, after the purchase of an additional 50% participation, of Ch$ 38 billion, a decrease of collections from derivatives contracts of
Ch$ 17 billion and investments in time deposits with a maturity greater than 90 days of Ch$ 16 billion, all of which were partially offset by the loss of control of combined entities for Ch$ 41 billion, due to the sale
of all the shareholdings in Maitenes and Aguas Santiago Poniente, proceeds from dividends classified as investment cash flow of Ch$ 13 billion and interest received of Ch$ 4 billion.

For the year ended December 31, 2015, net cash used in financing activities increased to Ch$ 273 billion from
Ch$ 159 billion in 2014. The main drivers of this change are described below.

The aggregate cash outflows from financing
activities were primarily due to:



| |  |  | Ch$ 140 billion of payments of bonds for Endesa Chile on a stand-alone basis.
| | - |  | -----------------------------------------------------------------------------



| |  |  | Ch$ 135 billion in dividend payments (including Ch$ 103 billion for Enersis Américas, on a stand-alone basis, Ch$ 22 billion by Endesa Chile, on a stand-alone basis, excluding
dividends paid to Enersis Chile, Ch$ 9 billion for Pehuenche, among others).
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Ch$ 60 billion of interest expense, mainly for Endesa Chile on a stand-alone basis.
| | - |  | -----------------------------------------------------------------------------------

These outflows were partially offset by cash inflows primarily due to:



| |  |  | Ch$ 40 billion in loans from related entities, including Endesa Chile and Chilectra Chile.
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | Ch$ 29 billion of net investment from parent companies.

liquidity risks resulting from the inability of our combined entities to transfer funds, please see Item 3. Key Information  D. Risk Factors  We depend in part on payments from our combined entities, jointly-controlled entities and
associates to meet our payment obligations.

We coordinate the overall financing strategy of our controlled combined entities. Our
operating combined entities independently develop their capital expenditure plans and finance their capital expansion programs through internally generated funds or direct financings. We, on a stand-alone basis, have no legal obligations or other
commitments to financially support our combined entities. We, on a stand-alone basis, currently have no debt obligations and are therefore not affected by any cross default provisions that could be triggered by combined entity defaults. Our combined
entities could be financed by us through intercompany loans. For information regarding our commitments for capital expenditures, see Item 4. Information on the Company  A. History and Development of the Company  Investments,
Capital Expenditures and Divestitures and our contractual obligations table set forth below under F. Tabular Disclosure of Contractual Obligations.

We have American Depositary Shares listed and that trade on the NYSE and may in the future access the international equity capital markets
(including SEC-registered ADS offerings) while our combined entity Endesa Chile has accessed the international equity capital markets, with an SEC-registered ADS offering on August 3, 1994. Endesa Chile has also issued bonds in the United
States (Yankee Bonds) and we and Endesa Chile may issue Yankee Bonds depending on liquidity needs in the future. Since 1996, Endesa Chile and its subsidiary Pehuenche have issued a total of US$ 2,770 million in Yankee Bonds.

The following table lists the Yankee Bonds issued by our combined entity, Endesa Chile, and the aggregate principal amount outstanding as of
December 31, 2015. The weighted average annual coupon interest rate for such bonds is 5.8%, without giving effect to each bonds duration, or put options.

The Endesa Chile revolving credit facility due July 2019 is governed by the laws of the State of New York and
does not contain a condition precedent requirement regarding the non-occurrence of a Material Adverse Effect (or MAE, as defined contractually) prior to a disbursement, allowing us full flexibility to draw on up to US$ 200 million
in the aggregate from such committed revolving facility under any circumstances, including situations involving an MAE. On February 29, 2016, Endesa Chile entered into a new syndicated senior unsecured revolving loan under similar conditions
due February 2020, which permit to draw on up to an additional US$ 200 million in the aggregate, of which US$ 150 million have been drawn as of the date of this Report.

We and Endesa Chile also borrow from banks in Chile under fully committed facilities under which a potential MAE would not be an impediment to
this source of liquidity. In 2013, Endesa Chile entered into 3-year bilateral revolving loans for an aggregate of UF 2.4 million (Ch$ 61 billion as of December 31, 2015) as set forth in the table below. These loans were closed voluntarily
in January 2016, before their due date, and were renewed for an aggregate amount of UF 2.8 million (Ch$ 73 billion using the exchange rate of December 31, 2015) with a 3-year term starting in March 2016.



|             |  |      |                           |  |          |  |               |                      |  |  |                      |  |  |  |   |

|             |  |      |                           |  |          |  |               | (in millions of UF$) |  |  | (in billions of UF$) |

As a result of the foregoing, we have access to fully committed undrawn revolving loans, both international
and domestic, for up to approximately Ch$ 203 billion in the aggregate as of December 31, 2015 and Ch$ 251 billion in the aggregate (using 2015 year-end exchange rate), considering the inclusion of Endesa Chiles renewed
bilateral revolving loan.

We and Endesa Chile also borrow routinely from uncommitted Chilean bank facilities with approved lines of
credit for approximately Ch$ 113 billion in the aggregate, none of which are currently drawn. Unlike the committed lines described above, which are not subject to MAE conditions precedent prior to disbursements, these facilities are not
guaranteed , and therefore could limit our liquidity under certain circumstances. Our combined entities also have access to uncommitted local bank facilities, for a total amount of Ch$ 97 billion, none of which are currently drawn.

Both we and Endesa Chile may also access the Chilean commercial paper market under programs that need to be registered with the SVS. Endesa
Chile has an outstanding program for a maximum of US$ 200 million. Finally, we can also have access to other types of financing, including supplier credits, leasing, among others.

As of December 31, 2015, we, on a stand-alone basis, had no debt obligations and was therefore not affected by any covenants or events of
default. Endesa Chiles outstanding debt facilities, with the exception of their Yankee Bonds, include financial covenants. The types of financial covenants, and their respective limits, vary from one type of debt to another. As of
December 31, 2015, the



75

##### Table of Contents

most restrictive financial covenant affecting Endesa Chile was the leverage ratio in connection with the bilateral revolving loan facility that were closed in January 2016. Under such covenant,
the maximum additional debt that could be incurred without a breach is Ch$ 1,236 billion. As of December 31, 2015 and as of the date of this Report, our combined entities are in compliance with the financial covenants contained in our
combined debt instruments.

As is customary for certain credit and capital market debt facilities, a significant portion of Endesa
Chiles financial indebtedness is subject to cross default provisions. Each of the revolving credit facilities described above, as well as all of Endesa Chiles Yankee Bonds, have cross default provisions with different definitions,
criteria, materiality thresholds, and applicability as to the combined entities that could give rise to a cross default.

The cross
default provisions for the Endesa Chile revolving credit facilities that are due in July 2019 and in February 2020, governed by the laws of the State of New York, refer to defaults of the borrower, without reference to any combined entity. Under
such credit facilities, only matured defaults of the borrower exceeding US$ 50 million qualify for a potential cross default when the principal exceeds US$ 50 million, or its equivalent in other currencies. In the case of a matured
default above the materiality threshold, the revolving credit facilitys lenders would have the option to accelerate if lenders representing more than 50% of the aggregate debt of a particular outstanding facility choose to do so.

Neither the local facility of Endesa Chile, which was closed in January 2016, nor the new facility due in March 2019 have cross default
provisions to debt other than the respective borrowers own indebtedness.

Cross default provisions of Endesa Chiles Yankee
Bonds may be triggered by its Chilean subsidiaries debt. A matured default of Endesa Chile or one of its subsidiaries could result in a cross default to Endesa Chiles Yankee Bonds if such matured default, on an individual basis, has a
principal exceeding US$ 30 million, or its equivalent in other currencies. In the specific case of the Endesa Chiles Yankee Bond issued in April 2014, maturing in 2024, the threshold is US$ 50 million, or its equivalent in
other currencies. In the case of a matured default above the materiality threshold, Yankee bondholders would have the option to accelerate if either the trustee or bondholders representing at least 25% of the aggregate debt of a particular series
then outstanding choose to do so. Finally, Endesa Chiles local bonds do not have cross default provisions arising from its subsidiaries.

All of Endesa Chiles Yankee Bonds, including those registered with the United States Securities and Exchange Commission, are
unsecured and not subject to any guarantees by any of our combined entities or parent companies, or contain any financial covenants.

Payment of dividends and distributions by our combined entities and affiliates represent an important source of funds for us. The payment of
dividends and distributions by certain combined entities and affiliates are subject to legal restrictions, such as legal reserve requirements, and capital and retained earnings criteria, and other contractual restrictions. Legal counsel informed us
of the current legal restrictions regarding the payment of dividends or distributions to us in Chile. We are currently in compliance with the legal restrictions, and therefore, they currently do not affect the payment of dividends or distributions
to us. Certain credit facilities and investment agreements of our combined entities may restrict the payment of dividends or distributions in certain special circumstances. For instance, one of Endesa Chiles UF-denominated Chilean bonds
restricts the amount of intercompany loans that Endesa Chile and its subsidiaries are allowed to lend to Enersis Américas or Enersis Chile. The threshold for such aggregate restriction of intercompany loans is US$ 100 million equal to
approximately Ch$ 71 billion. For a description of liquidity risks resulting from our company status, please see Item 3. Key Information  D. Risk factors We depend in part on payments from our combined entities,
jointly-controlled entities and associates to meet our payment obligations.

Our estimated capital expenditures for 2016 through
2020 amount to Ch$ 1,304 billion, of which Ch$ 1,243 billion are considered non-discretionary investments. Maintenance capital expenditures is considered non-discretionary because we need to maintain the quality and operation standards
required for our facilities, but we do have some flexibility regarding the timing for these investments. We consider the investment in expansion projects under execution as non-discretionary expenditures, such as those for Los Cóndores, as
well as water rights. We consider the remaining Ch$ 61 billion as discretionary capital expenditures. The latter includes expansion projects that are still under evaluation, in which case we would undertake them only if deemed profitable.

We do not currently anticipate liquidity shortfalls affecting our ability to satisfy the material obligations described in this Report. We
expect to be able to refinance our combined indebtedness as it becomes due, fund our purchase obligations outlined previously with internally generated cash and fund capital expenditures with a mixture of internally generated cash and borrowings.

Our combined entities are engaged in the generation and
distribution of electricity in Chile. Our businesses are subject to a wide range of conditions that may result in significant variability in our earnings and cash flows from year to year.

Our net income is principally the result of operating income from our generation and distribution businesses, and non-operating income
including primarily income arising from related companies accounted for under the equity method, interest expense and tax expense.

In our
generation business, our operating income is impacted by the combined effect of several factors including our contracted electricity prices, prevailing hydrological conditions, the price of fuels used to generate thermal electricity, contracted
obligations, generation mix, and the electricity prices prevailing in the spot market, among others. The combined effect of many, and sometimes all, of these factors impacts our operating income, which can be more or less favorable from year to
year. For example, for the year ended December 31, 2015, our operating income increased by 63.5 % as compared to the same period in 2014 because of a better combination of these factors, as described in further detail in Item 5.
Operating and Financial Review and Prospects  A. Operating Results  2. Analysis of results of operations for the Years Ended December 31, 2015 and 2014.

One of the main drivers of our results of operations of our electricity generation business is our sale prices and energy costs. Generally,
the quantity of electricity sold has been relatively stable over time, with increases reflecting economic and demographic growth. Our profits from contracted sales are driven by the ability to generate or buy electricity at a cost lower than the
contracted price. However, the applicable price for sales and purchases for electricity sold and purchased in the spot market is much harder to predict because the spot generation price is influenced by many factors. In general, abundant
hydrological conditions lower spot prices while dry conditions increase them. However, our operating income may not be impacted even when we are required to buy at high prices in the spot market if our commercial policy is appropriately managed. Our
goal is to have a conservative and well balanced commercial policy, which aims at controlling relevant variables, provides stability to profits, and mitigates our exposure to the volatility of the spot market by contracting sales of a significant
portion of our expected electricity generation through long-term electricity supply contracts. Our optimal level of electricity supply commitments is one that allows us to protect ourselves against low marginal cost conditions, such as those
existing during the rainy season, while still taking advantage of high marginal cost conditions, such as higher spot market prices during dry years. In order to determine the optimal mix of long-term contracts and sales in the spot market:
(i) we project our aggregate generation taking into consideration our generation mix, the incorporation of new projects under construction and a dry hydrology scenario, (ii) create demand estimates using standard economic theory, and
(iii) forecast the systems marginal cost using proprietary stochastic models.

Spot prices could also be affected by
international prices for commodities such as fuel oil, coal and LNG, since Chile does not produce coal or hydrocarbons in any significant quantities. Fuel prices affect our results since commodity prices directly impact generation costs of our
thermal power plants. Commodity prices, mainly oil, have materially decreased since the second half of 2014 and we expect that this trend will continue until the end of 2016, when oil prices are expected to begin increasing. This decreasing trend
will likely lower our costs in the generation business, but they also depend on other factors such as spot prices, generation mix, hydrology conditions and our contractual surpluses/deficits. As described below, our contracted sales prices are
indexed to coal, Brent and Henry Hub prices; therefore, sales prices will also be affected by variations of commodity prices, reducing in part our results. Commodities are contracted for long-term period (10-15 years) and we try to determine the
indexation formula based on our cost forecasts. The indexation of long-term sale prices tries to hedge revenues and operating costs, which are also constantly monitored and analyzed to reach favorable hedge positions in the short-term as well.

Between January and March 2016, marginal costs in the SIC decreased compared to the previous year, was due to an increase of NCRE generation,
a decrease of the commodity prices and a greater availability of thermal electricity generation. We purchased energy in the spot market at lower prices because our contracted sales exceeded our own generation. Also, we increased our thermal
generation because of the availability of the Bocamina thermal power plants. If this combination of factors continues, it is likely to have a positive effect on our results.

In order to mitigate the risk of fuel cost increases, we have entered into supply contracts to cover part of the fuel needed to operate the
thermal generation units, which operate with coal, natural gas, diesel, and fuel oil. Through an equity interest in GNL Quintero and GNL Chile, and a Long Term Gas Supply Agreement with GNL Chile, we are the only electricity company in Chile with
direct access to the LNG terminal at Quintero Bay (the only facility of its kind in the SIC market). This enhances our position to manage fuel supply risks, especially when facing increasing fuel costs scenarios. This is becoming more important as
there is an increasing trend to penalize fuel intensive technologies, such as coal and diesel, which have greater environmental impacts. However, in March 2016, Gener and Colbún, our main competitor in the SIC, entered into a 20-year
agreements with GNL Chile for an additional capacity that is expected to be available by 2021. Both companies will have the same rights as the current terminals client, including Endesa Chile.

In July 2013, Endesa Chile successfully renegotiated a LNG sale and purchase agreement with
British Gas. This renegotiation modified some conditions of the original contract, allowing Endesa Chile to secure its long-term LNG supply at competitive prices, with significant flexibility and at capacities sufficient for its current and future
needs.

Endesa Chile has also contracted capacity in the LNG truck loading facility (TLF) in the Quintero LNG Terminal, allowing it to
sell natural gas to industrial customers. In August 2014, the first load of LNG was successfully delivered to Maersks satellite regasification facility. During 2014, a 20-year sale and purchase agreement was signed with GasValpo (an unrelated
gas distribution company) to distribute natural gas using the TLF for new customers in various cities in Chile. The first stage started its operations during August 2015, supplying the city of Talca (270 km south of Santiago). During November 2015,
the first load of GNL was delivered to supply cities of Coquimbo and La Serena. During December 2015, the first load of GNL was delivered to supply the city Los Andes. Other plants are currently in advanced construction and will begin operation
during the first quarter of 2016.

In January 2015, Endesa Chile entered into an agreement with Intergas (an unrelated gas distribution
company) to supply LNG by trucks to the city of Temuco (700 km south of Santiago). This supply arrangement will start during the first quarter of 2016.

Endesa Chile also exercised a priority option to purchase additional regasification capacity as part of an expansion at the Quintero LNG
Terminal. This allows Endesa Chile to increase its regasification capacity from 3.2 million cubic meters per day to 5.4 million cubic meters per day during the first quarter of 2015. This expansion will allow our San Isidro and Quintero
power plants to generate additional thermal electricity, to secure the LNG supply necessary for potential new power plants and to develop new businesses, such as the leasing agreement signed with Gener during 2015, which allowed Endesa Chile to
utilize Geners Nueva Renca combined-cycle power plant to generate electricity with its LNG.

Between January to December 2015, 723
kTons of coal were consumed in Tarapacá and Bocamina power plants. Due to judicial issues, units I and II of Bocamina power plant stopped their operations for 8 and 18 months, respectively and therefore, deliveries from a short term
agreements signed between Endesa Chile and Endesa Generación S.A., a Spanish subsidiary of Enel, to supply the Bocamina power plants was deferred to the Tarapacá power plant. This agreement was effective until the end of 2015.

Between February 12, 2016 to February 26, 2016, due to high energy requirements by the Argentine system and pursuant to an existing
agreement between Gener and other generators in the SING, including Endesa Chile, the GasAtacama power plant was able to export energy to Argentina. Total energy exported was approximately 40 GWh.

Other factors that affect operating income include transmission costs incurred when delivering electricity from its source to end consumers.
The transmission charge is set by the Chilean regulator, and has tended to remain stable over time. A new transmission law is expected to be enacted during the third quarter of 2016 and it is expected that from 2019 to 2034, the transmission cost
for the use of the main transmission system will progressively be transferred to customers, who will fully assume that cost beginning in 2035.

As a consequence of hydrological conditions, the stoppage of Bocamina I and II and our requirement to comply with our contracted obligations,
we have been a net purchaser of electricity in the spot market since the second half of 2014, a trend that increased in 2015 compared to 2014. During this period, average spot prices (measured in US$/MWh) have been decreasing. The CDEC-SIC
forecasted that the 2016 energy costs, and therefore spot prices, would decrease significantly compared to the average of previous years, mainly due to the entry of new efficient generation capacity, low cost of fuels and the increase of power
plants based on NCRE. This decrease may be greater depending on the availability of water for generation.

NCRE energy generation will
increase in the upcoming years. According to the Observatorio de la Inversión (Issue No. 14) prepared by the Sociedad de Fomento Fabril (SOFOFA in its Spanish acronym), the companies trade association, in
December 2015, 279 NCRE projects, representing 25,010 MW of gross electricity production, were in development. It is estimated that in 2017, NCREs will represent approximately 40% of the estimated total energy generation in the SIC and SING
systems for that year, with most NCREs concentrated in the SIC. This tendency is a direct consequence of several initiatives that the Chilean government is promoting with the Energy Agenda program, which aim to have by 2050,
70% of the national generation of electricity to be produced by NCRE.

Another main factor affecting our net income is our contractual
sales. Currently, our contracted sales are not standardized and the terms and conditions of these sale contracts are individually negotiated. Typically, when we negotiate these sale contracts, we try to set the price at a premium over future
expected spot prices so as to mitigate the risk of future increases in spot prices. However, the premium can vary substantially depending on a variety of conditions. The proportion of contracted sales with regulated customers (distributors) has
increased in relation to the non-regulated customers. This allows us to have consistent prices for longer periods, normally between 10 to 20 years, which combined with our conservative commercial policy, provides for our profitability. Most
regulated tariffs are composed of 70% U.S. consumer price index (CPI) and 30% commodities prices. Recently, the tariff components have been 25% of U.S. CPI, 25% Henry Hub prices, 25% Brent prices and 25% coal prices, in order to better
reflect higher commodity dependence. We expect that during the next three years, regulated tariff rates in Chile will remain fairly stable, without material changes.

Our tax expense increased significantly in 2014 as a consequence of a tax reform enacted in Chile
on September 29, 2014, which established a gradual increase in the taxation rate until 2018. In accordance with IFRS, the main effect of the new Chilean tax reform was applied as a one-time adjustment to our net deferred tax liabilities as of
September 30, 2014 and recognized in our statement of comprehensive income. It is expected that this reform will slightly affect our results in the future, considering its main impacts on deferred taxes have been already recognized. For more
detail see Item 10. Additional Information  E. Taxation  Chilean Tax Considerations.

For more detail on how each
of these factors impact the net income of our electricity generation and distribution businesses, see Item 5. Operating and Financial Review and Prospects  A. Operating Results  1. Discussion of Main Factors Affecting Operating
Results and Financial Condition of the Company.

We expect reasonably good operating performance during the coming years given the
macroeconomic perspective for Chile. Despite current uncertainties concerning the global economy, there is favorable expectation for Chiles growth during the next five years, including an expected 1.9% growth in gross domestic product in 2016,
based on Latin American Consensus Forecasts published by Consensus Economics Inc. on March 14, 2016, and the annual electricity demand growth over the next five years is expected to be 2.5%.

On the other hand, development of new generation facilities in Chile has always lagged behind demand growth. However, due to growing
environmental restrictions, transmission line saturation, obstacles for fuel transportation, and scarcity of places where to locate plants, these new projects involve higher development costs than in the past.

Enel, our ultimate controller, has announced that it will no longer build coal power plants because it considers the technology to be
obsolete, and the company expects to have no CO2emissions by 2050. Closure of these coal power plants are scheduled between now and 2040 or 2045. Their capacity must be substituted by other
types of generation. Natural gas power plants are not an option because of the CO2 costs and current carbon capture and storage technology are not economically viable and therefore, the focus
will be on NCRE.

We expect that average electricity prices will rise to recognize these higher costs. This could increase the value of
our assets, especially in the case of hydroelectric power plants, which have lower production costs, and thus have greater profitability in scenarios of increasing prices to end customers. We expect this situation will also impact long term spot
prices positively. Long term contracts awarded to our combined entities in different bids have already incorporated these expected price levels. Currently, 15.4% of our expected annual generation is sold under contracts with terms of at least ten
years and an additional 70.5% under contracts with terms of at least five years.

With respect to our distribution business, our operating
income for the year ended December 31, 2015 decreased by 3.1% as compared to the same period of 2014. In connection with the distribution segment tariffs, and taking into account the future periodic review process in Chile, we expect that the
regulator will continue to recognize investments, encourage efficiency, and establish prices that will allow for an appropriate return on our investment. We also anticipate that our distribution company will maintain its profitability during the
period between periodic tariff setting processes, according to price cap tariff model, due to growth and economies of scale. After tariffs have been set, the companies have the opportunity to increase their efficiency, and obtain extra profits
associated with such efficiencies, during the period subsequent to each new tariff setting.

Schedule for distribution tariff revisions is well defined for the following years:



LOGO

Although the price at which distribution company purchases electricity has an impact on the price at which
it is sold to end customers, it does not have an impact on our profitability since the cost of electricity purchased is passed to end customers through tariffs. Regulation dictates that purchase contracts must be made through long-term contracts and
are the result of a regulated tender.

During 2016, Chilectra Chile will implement smart meters in its concession area, which will permit
bi-directional communication, digitized and interconnected networks, and will enable our consumers improve energy efficiency.

There can
be no assurance that past performance will be indicative of future performance with respect to our businesses. Any significant change with respect to hydrological conditions, fuel or electricity prices, among other factors, could affect our
operating income in the generation business. More broadly, any significant change with respect to economic or population growth, as well as changes in the regulatory regimes in Chile, among other factors, could affect our operating income.
Variability in our earnings and cash flows can also arise from non-operating factors as well, such as foreign currency exchange rates. For further information regarding our 2015 results compared with those recorded in previous periods, please see
 A. Operating Results  Results of Operations for the years ended December 31, 2015 and 2014 and  A. Operating Results  Results of Operations for the Years Ended December 31, 2014 and 2013.
Investors should not look at our past performance as indicative of future performance.

We expect that we will continue generating
substantial operating cash, which can be used to finance a significant part of our capital expenditure plan. If needed, our shareholders can also decrease the dividend payout ratio, subject to certain minimum legal restrictions, in order to finance
our investment plan and future growth.

B. Compensation.

At the ESM held on
December 18, 2015, the shareholders of Enersis Américas approved the compensation policy for our Board of Directors. Directors are paid an annual variable fee equivalent to 0.1% of our net earnings for the current year based on the
combined financial statements. Directors are also paid a monthly fee, in advance, depending on their attendance at Board meetings and their participation as director of any of our combined entities. Director compensation consists of a monthly fixed
compensation of UF 180 per month and an additional fee of UF 66 per meeting, depending on attendance to Board meetings. The monthly fixed fees are considered as advances on the annual variable fee and creditable against that amount.
Once our net earnings are approved at the OSM of the following year, the difference between the accrued annual variable fee and the total fees paid in advance will be paid to directors, but only if the resulting amount is positive. The Chairman of
the Board is entitled to double the compensation compared to other directors under this policy, while the Vice Chairman receives fixed compensation higher than the directors but lower than the Chairman. The members of our Directors
Committee are paid a variable annual fee, equivalent to a percentage of our net earnings of the current year. If a Director serves on one or more Boards of Directors of the subsidiaries and/or related companies or serves as director of other
companies or corporations in which the economic group holds an interest directly or indirectly, the Director can only receive compensation in one of these Boards of Directors. Executive Officers of our Company and/or of our subsidiaries or related
companies will not receive compensation in the case that they serve as Director of any subsidiary, related company or are affiliated in any way to our Company.

##### Table of Contents

We do not disclose, to our shareholders or otherwise, any information about an individual
Executive Officers compensation. Executive Officers are eligible for variable compensation under a bonus plan. The annual bonus plan is paid to our Executive Officers for achieving company-wide objectives and for their individual contribution
to our results and objectives. The annual bonus plan provides for a range of bonus amounts according to seniority level and consists of a certain multiple of gross monthly salaries.

We entered into severance indemnity agreements with all of our Executive Officers, pursuant to which we will pay a severance indemnity in the
event of voluntary resignation or termination by mutual agreement among the parties. The severance indemnity does not apply if the termination is due to willful misconduct, prohibited negotiations, unjustified absences or abandonment of duties,
among other causes, as defined in Article 160 of the Chilean Labor Code. All of our employees are entitled to legal severance pay if terminated due to our needs, as defined in Article 161 of the Chilean Labor Code.

C. Board Practices.

Corporate Governance

We are managed by a Board of Directors in accordance with our by-laws. The Board initially consisted of seven directors who were
elected by shareholders of Enersis Américas at the ESM held on December 18, 2015 to hold office until the first OSM of our shareholders held on April 28, 2016. At the 2016 OSM, the entire Board of Directors consisting of seven
members was elected to a three-year term. Following the end of their term, they may be re-elected or replaced. Directors can be re-elected indefinitely. Staggered terms are not permitted under Chilean law. If a vacancy occurs on the Board of
Directors during the three-year term, the Board of Directors may appoint a temporary director to fill the vacancy. Any vacancy triggers an election for every seat on the Board of Directors at the next OSM. Members of the Board of Directors do not
have service contracts with us or with any of our combined entities that will provide them benefits upon termination of their service.

Chilean corporate law provides that a companys Board of Directors is responsible for the management and representation of a company in
all matters concerning its corporate purpose, subject to the provisions of the companys by-laws and the stockholders resolutions.

Our corporate governance policies are included in the following policies or procedures: Manual for the Management of Information of Interest
to the Market (the Manual), the Human Rights Policy (Política de Derechos Humanos), the Code of Ethics and a Zero Tolerance Anti-Corruption Plan (ZTAC Plan), the Penal Risk Prevention Model, the
Guidelines 231: Guidelines applicable to non-Italian subsidiaries in accordance with Legislative Decree No. 231 of June 8, 2001 and procedures issued in compliance with General Regulation No. 385 issued by the SVS.

In order to ensure compliance with Securities Market Law No. 18,045 and SVS regulations, our Board of Directors approved the Manual at
the meeting held on February 29, 2016 and ratified such decision at its meeting held on March 23, 2016. This document addresses applicable standards regarding the information in connection with transactions of our securities and those of
our affiliates, entered into by directors, management, principal executives, employees and other related parties; the existence of blackout periods for such transactions undertaken by directors, principal executives and other related parties, the
existence of mechanisms for the continuous disclosure of information that is of interest to the market and mechanisms that provide protection for confidential information. The Manual will be posted on our website at www.enersischile.cl. The
provisions of this Manual apply to the members of our Board, as well as our executives and employees who have access to confidential information, and especially those who work in areas related to the securities markets.

Our Board of Directors approved a procedure for relationship between People Politically Exposed (Procedimiento Personas Expuestas y
Conexas) and our Company, which established a specific regulation for their commercial and contractual relationships.

The Human
Rights Policy incorporates and adapts the United Nations general principles related to human rights into the corporate reality.

Our Board of Directors approved a ZTAC Plan at its first meeting held on February 29, 2016 in order to supplement the aforementioned
corporate governance regulations and ratified such decision at its meeting held on March 23, 2016. The Code of Ethics is based on general principles such as impartiality, honesty, integrity and other ethical standards of similar importance, all
of which are expected from our employees. The ZTAC Plan reinforces the principles included in the Code of Ethics, but with special emphasis on avoiding corruption in the form of bribes, preferential treatment, and other similar matters.

In order to comply with Law No. 20,393 enacted on December 2, 2009, which imposes criminal responsibility on legal entities for
the crimes of asset laundering, financing of terrorism and bribing of public officials, our Board of Directors approved the Penal Risk Prevention Model at its first meeting held on February 29, 2016 and ratified such decision at its meeting
held on March 23, 2016. The law encourages companies to adopt this model, whose implementation involves compliance with managerial and supervision duties. The adoption of the Penal Risk Prevention Model mitigates, and in some cases relieves,
the effects of criminal responsibility even when a crime is committed. One of the elements of this model is the appointment of the Penal Risk Prevention Officer, who was also appointed by our Board at the same meeting. Mr. Alain Rosolino, who
currently serves as our Internal Audit Officer, was appointed as our Penal Risk Prevention Officer.

On February 29, 2016, our Board of Directors also approved the Guidelines 231:
Guidelines applicable to non-Italian subsidiaries in accordance with Legislative Decree 231 of June 8, 2001 (Guidelines 231) and ratified such decision at its meeting held on March 23, 2016. The Guidelines 231
is defined by Italian Legislative Decree No. 231, which was enacted on June 8, 2001. It establishes a compliance program that identifies the behaviors expected of related parties for the non-Italian subsidiaries of Enel. Given that our
ultimate parent company, Enel, has to comply with Italian Legislative Decree No. 231, which establishes management responsibility for Italian companies as a consequence of certain crimes committed in Italy or abroad, in the name of or for
the benefit of such entities, including those crimes described in Chilean Law No. 20,393, these guidelines set a group of measures, with standards of behavior expected from all employees, advisers, auditors, officials, directors as well as
consultants, contractors, commercial partners, agents and suppliers. Legislative Decree No. 231 includes various activities of a preventive nature that are coherent with and integral to the requirements and compliance with Chilean Law
No. 20,393, which deals with the criminal responsibility of legal entities. These guidelines are supplementary to the standards included in the Code of Ethics and the ZTAC Plan.

On November 29, 2012, the SVS issued General Regulation No. 341 which established regulations for the disclosure of information with
respect to the standards of corporate governance compliance adopted by publicly held limited liability corporations and set the procedures, mechanisms and policies that are indicated in the Appendix to the regulation. The objective of this
regulation is to provide credible information to investors with respect to good corporate governance policies and practices adopted by publicly held limited liability corporations, which include us, and permit entities like stock exchanges to
produce their own analyses to help the various market participants to understand and evaluate the commitment of companies. General Regulation No. 341 was substituted by General Regulation No. 385, issued by the SVS on June 8,
2015. This regulation has similar objectives than the former General Regulation No. 341, but includes additional issues, by the way of separating each policy in several more detailed policies. Subjects such as non discrimination, inclusion and
sustainability are particularly important in this new regulation. The Appendix of General Regulation No. 385 is divided into the following four sections with respect to which companies must report the corporate practices that have been adopted:
(i) the functioning and composition of the board, (ii) relations between the company, shareholders and the general public, (iii) risk management and control, and (iv) assessment by a third party. Publicly held limited liability
corporations should send the information with respect to corporate governance practices to the SVS, no later than March 31 of each year, using the contents of the Appendix to this regulation as criteria. If none of them is adopted, the company
must explain its reasons to the SVS. The information should refer to December 31 of the calendar year prior to its dispatch. At the same time, such information should also be at the publics disposal on the companys website and must
be sent to the stock exchanges.

Compliance with the New York Stock Exchange Listing Standards on Corporate Governance

The following is a summary of the significant differences between our corporate governance practices and those applicable to U.S. domestic
issuers under the corporate governance rules of the NYSE:

Independence and Functions of the Directors Committee (Audit Committee)

10% or more of the capital stock or has been a director, manager, administrator or principal officer of an entity that has provided consulting or legal services for a relevant consideration or external audit services to the persons listed in
(i) above; and (v) has been a partner or a shareholder that has controlled, directly or indirectly, 10% or more of the capital stock or has been a director, manager, administrator or principal officer of the principal competitors,
suppliers or customers. In case there are not sufficient independent directors on the Board to serve on the Directors Committee, Chilean law determines that the independent director nominates the rest of the members of the Directors
Committee among the remaining Board members that do not meet the Chilean law independence requirements. Chilean law also requires that all publicly held limited liability stock corporations that have a market capitalization of at least
UF 1,500,000 (Ch$ 38.4 billion as of December 31, 2015) and at least 12.5% of its voting shares are held by shareholders that individually control or own less than 10% of such shares, must have at least one independent
director and a Directors Committee.

Under the NYSE corporate governance rules, all members of the Audit Committee must be
independent, subject to a phase-in period for compliance for spin-off companies. The Audit Committee of a U.S. company must perform the functions detailed in, and otherwise comply with the requirements of NYSE Listed Company Manual
Rules 303A.06 and 303A.07. As of July 31, 2005, non-U.S. companies have been required to comply with Rule 303A.06, but not with Rule 303A.07. We currently comply with the independence and the functional requirement of
Rule 303A.06.

##### Table of Contents

Pursuant to our by-laws, all members of the Directors Committee must satisfy the
requirements of independence, as stipulated by the NYSE. The Directors Committee is composed of three members of the Board and complies with Chilean law, as well as with the criteria and requirements of independence prescribed by the
Sarbanes-Oxley Act (SOX), the SEC and the NYSE. As of the date of this Report, the Directors Committee complies with the conditions of the Audit Committee as required by the SOX, the SEC and the NYSE corporate governance rules. As
a result, we have a single Committee, the Directors Committee, which includes among its functions the duties performed by the Audit Committee.

Our Directors Committee performs the following functions:



| |  |  | review of financial statements and the reports of the external auditors prior to their submission for shareholders approval;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------



| |  |  | formulate proposals to the Board of Directors, which will make its own proposals to shareholders meetings, for the selection of external auditors and private rating agencies;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | review of information related to our transactions with related parties and reports the opinion of the Directors Committee to the Board of Directors;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the examination of the compensation framework and plans for managers, executive officers and employees;
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | the preparation of an Annual Management Report, including its main recommendations to shareholders;
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | provide information to the Board of Directors about the convenience of recruiting external auditors to provide non-auditing services, when such services are not prohibited by law, depending on whether such services
might affect the external auditors independence;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | oversee the work of external auditors;
| | - |  | --------------------------------------



| |  |  | review and approval of the annual auditing plan by the external auditors;
| | - |  | -------------------------------------------------------------------------



| |  |  | evaluate the qualifications, independence and quality of the auditing services;
| | - |  | -------------------------------------------------------------------------------



| |  |  | elaborate on policies regarding employment of former members of the external auditing firm;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | review and discuss problems or disagreements between management and external auditors regarding the auditing process;
| | - |  | ---------------------------------------------------------------------------------------------------------------------



| |  |  | establish procedures for receiving and dealing with complaints regarding accounting, internal control and auditing matters;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------



| |  |  | any other function mandated to the committee by the by-laws, our Board of Directors or our shareholders.
| | - |  | --------------------------------------------------------------------------------------------------------

Corporate Governance Guidelines

The NYSEs corporate governance rules require U.S.-listed companies to adopt and disclose corporate governance guidelines. Chilean law
provides for this practice through the disclosure of the procedures related to the General Resolution No. 385 and the Manual. We have also adopted the codes of conduct described above, and our by-laws include provisions that govern the
creation, composition, attributions, functions and compensation of both Directors and Audit Committees described above.

All Chilean employees who are dismissed for reasons other
than misconduct are entitled by law to a severance payment. According to Chilean law, permanent employees are entitled to a basic payment of one-months salary for each year (or a six-month portion thereof) worked, subject to a limit of a total
payment of no more than 11 months pay for employees hired after August 14, 1981. Severance payments to employees hired prior to that date consist of one-months salary for each full year worked, not subject to any limitation on
the total amount payable. Under our collective bargaining agreements, we are obligated to make severance payments to all covered employees in cases of voluntary resignation or death in specified amounts that increase according to seniority and may
exceed the amounts required under Chilean law.

##### Table of Contents

We currently have two collective bargaining agreements in Chile, which were transferred from
Enersis Américas. The first one was signed in July 2015 and it will be in force until July 2019. The second one was signed in January 2016 and will expire in December 2019. Chilectra has five collective bargaining
agreements, all of them signed in 2012, which expire in December 2016. Empresa Eléctrica de Colina has one collective bargaining agreement signed in 2015, which expires in October 2019. SIEI has one agreement which expired in December
2019. Endesa Chile has four collective bargaining agreements in Chile, which will expire between 2015 and 2017.



|E. | Share Ownership.
|-- | ----------------

At the 2016 OSM, the Board of Directors was elected. To the best of
our knowledge, none of our directors or officers owns more than 0.1% of our shares or owns any stock options. It is not possible to confirm whether any of our directors or officers has a beneficial, rather than direct, interest in our shares.
To the best of our knowledge, any share ownership by all of our directors and officers, in the aggregate, amounts to significantly less than 10% of our outstanding shares.



|Item 7. | Major Shareholders and Related Party Transactions
|------- | -------------------------------------------------



|A. | Major Shareholders.
|-- | -------------------

We have only one class of capital stock and Enel, our ultimate
controlling stockholder, has no different voting rights than our other shareholders. As of April 26, 2016, 49,092,772,762 shares of our common stock outstanding were held by 6,816 stockholders of record. There were five record holders of our
ADSs, as of such date.

It is not practicable for us to determine the number of our ADSs or our common stock beneficially owned in the
United States, as the depositary for our ADSs only has knowledge of the record holders, including the Depositary Trust Company and its nominees. As a result, we are not able to ascertain the domicile of the expected final beneficial holders
represented by Enersis Chile ADS record holders. Likewise, we cannot readily determine the domicile of any of the expected foreign stockholders who will hold our common stock, either directly or indirectly. On October 23, 2014, Endesa S.A., a
Spanish subsidiary of Enel, sold its direct and indirect ownership interest in shares of Enersis Américas to Enel Iberoamérica, a wholly-owned Spanish subsidiary of Enel. As a result of this transaction, Enel owned 60.6% of Enersis
Américas through Enel Latinoamérica (40.3%) and Enel Iberoamérica (20.3%).

On April 26, 2016, Enersis
Américas distributed our shares to the shareholders of Enersis Américas, including Enel Latinoamérica and Enel Iberoamérica, as part of the Spin-Off described above.

The following table sets forth certain information concerning the expected ownership of Enersis Chile common stock as of April 28, 2016,
with respect to each stockholder known by us that is expected to own more than 5% of the outstanding shares of Enersis Chile common stock:



|                      |  |                         |                |  |                                   |  |       | 
|--------------------- |  | ----------------------- | -------------- |  | --------------------------------- |  | ----- | 
|                      |  | Number of Shares  Owned |                |  | Percentage of Shares  Outstanding | 
|Enel Latinoamérica(1) |  |                         | 19,794,583,473 |  |                                   |  | 40.3% | 
|Enel Iberoamérica     |  |                         | 9,967,630,058  |  |                                   |  | 20.3% | 



|(1) | Enel Latinoamérica is wholly-owned by Enel Iberoamérica, which in turn is wholly-owned by Enel.

Enel is an Italian energy company with multinational operations in the power and gas markets. Enel operates in over 30 countries across 4
continents, producing energy through a net installed capacity of more than 89 GW and distributes electricity and gas through a network of approximately 1.9 million kilometers. With over 61 million users worldwide, Enel has the largest
customer base among European competitors and figures among Europes leading power companies in terms of installed capacity and reported EBITDA.

|B. | Related Party Transactions.
|-- | ---------------------------

Article 146 of Law No. 18,046 (the Chilean
Companies Act) defines related-party transactions as all transactions involving a company and any entity belonging to the corporate group, its parent companies, controlling companies, subsidiaries or related companies, board members, managers,
administrators, senior officers or company liquidators, including their spouses, some of their relatives and all entities controlled by them, in addition to individuals who may appoint at least one member of the companys board of directors or
who control 10% or more of voting capital, or companies in which a board member, manager, administrator, senior officer or company liquidator has been serving in the same position within the last 18 months. The law establishes that in the event that
these persons fulfill the requirements established by Article 146, such persons must immediately inform the Board of Directors of their related-party nature or such other group as the Board may appoint for that purpose. As required by law,
related-party transactions must comply with corporate interests, as well as prices, terms and conditions prevailing in the market at the time of their approval. They must also meet all legal requirements, including acknowledgement and
approval of the transaction by the board (excluding the affected directors), by the ESM (in some cases, with requisite majority approval) and by any applicable regulatory procedures.

The aforementioned law, which also applies to our affiliates, also provides for some exceptions, stating that in certain cases, Board approval
would suffice for related-party transactions, pursuant to certain related-party transaction thresholds and when such transactions are conducted in compliance with the related-party policies defined by the companys board.
Accordingly, during 2016, our Board of Directors will adopt a related-party transaction policy (política de habitualidad) which, when approved, will be available on our website.

If a transaction is not in compliance with Article 146, this would not affect the transactions validity, but we or our shareholders may
demand compensation from the individual associated with the infringement as provided under law, and reparation for damages.

It is our
policy that all cash inflows and outflows of its Chilean combined entities be managed through its centralized cash management policy. It is a common practice in Chile to transfer surplus funds from one company to another affiliate that has a cash
deficit. These transfers are carried out through either short-term loans or through structured inter-company loans. Under Chilean laws and regulations, such transactions must be carried out on an arms-length basis. All of these transactions
will be subject to the supervision of our Directors Committee. As of April 26, 2016, these transactions were priced at TIP (a Chilean variable interest rate) plus 0.05% per month.

Our combined entity Endesa Chile has received four structured loans from Enersis Américas, primarily to satisfy working capital needs.
As of April 28, 2016, the outstanding balance was comprised of a US$ 250 million loan at a fixed annual interest rate of 1.38%. Endesa Chile has also received short-term loans from its Chilean subsidiaries, primarily to satisfy working
capital needs. As of April 28, 2016, the outstanding balance for such loans was US$ 295 million comprised of a US$248 million loan from Gas Atacama and a US$46 million from Pehuenche.

Our combined entity SIEI has granted short term loans to our related parties in Latin America, primarily to satisfy working capital needs. As
of December 31, 2015, the account receivable was composed of a US$ 66 million from Enersis Américas.

Intercompany
Arrangements Related to the Spin-Off

Enersis Américas does not own any of our common stocks or ADSs and we do not own any
Enersis Américas common stocks or ADSs. Under Chilean law, Enersis Américas remains jointly and severally liable for the obligations of Enersis Américas assumed by us pursuant to the Spin-Off. Such liability, however, will not
extend to any obligation to a person or entity that has given its express consent relieving Enersis Américas of such liability and approving the Spin-Off.

There are a variety of contractual relationships between Enersis Américas and us to provide for ongoing relationships. They fall into two
broad categories:

Arrangements Related to the Spin-Off. The separation of the two companies and the transfer of certain assets and
liabilities of Enersis Américas to us were effected by the action of the shareholders of Enersis Américas at the Enersis Américas ESM held on December 18, 2015.

Post-Spin-OffIntercompany Services. We entered into new intercompany agreements under which we provide services directly and
indirectly to Enersis Américas, Endesa Américas and Chilectra Américas following the Spin-Off. As a result of the Spin-Off, existing intercompany agreements of Enersis Américas with Endesa Chile and Chilectra Chile were novated
with us as the new counterparty. To a much lesser extent, we may require services from Enersis Américas and from SIEI. The services to be rendered by us include certain legal, finance, capital markets, financial compliance, accounting, investor
relations, human resources, communications, security, training and development, relations with contractors, risk management, IT services, tax services and other corporate support and administrative services. These services are provided and charged
at market prices if there is a comparable service. If there are no comparable services in the market, they will be provided at cost plus a specified percentage.

As of the date of this Report, the abovementioned transactions have not experienced material changes. For more information regarding
transactions with related parties, refer to Note 11 of the Notes to our combined financial statements.

Legal Proceedings

We and our combined entities are parties to legal proceedings arising in the ordinary course of business. We believe it is unlikely that any
loss associated with pending lawsuits will significantly affect the normal development of our business.

##### Table of Contents

For detailed information as of December 31, 2015 on the status of the material pending
lawsuits that have been filed against Enersis and its subsidiaries, please refer to Note 36.3 of the Notes to our combined financial statements. Please note that since March 1, 2016, we are the defendant instead of Enersis Américas
for all legal proceedings originating from our former Chilean businesses.

In relation to the legal proceedings reported in the Notes to
our combined financial statements, we use the criteria of disclosing lawsuits above a minimum threshold of US$ 9 million of potential impact to us, and, in some cases, qualitative criteria according to the materiality of the impact in the
conduct of our business. The lawsuit status includes a general description, the process status and the estimate of the amount involved in each lawsuit.

Dividend Policy

Our Board of Directors
establishes a definitive dividend payable each year, accrued in the prior year, which cannot be less than the legal minimum of 30% of the annual net income. Additionally, the shareholders of Enersis Américas agreed to consider a
percentage of Enersis Américas 2015 annual consolidated net income as our 2015 annual consolidated net income at the ESM held on December 18, 2015. The initial definitive dividend payout will be equal to 50% of the annual
consolidated net income of Enersis Américas (before the Spin-Off) for fiscal year 2015. Since an interim dividend for Enersis Américas was already paid in January 2016, the remainder of the definitive dividend will be divided between
the continuing company, Enersis Américas, and us. Therefore, in May 2016, our shareholders are expected to receive a dividend of Ch$ 2.09338 per share of common stock and shareholders of Enersis Américas are expected to receive a
dividend of Ch$ 3.40599 per share of common stock.

The interim dividend that will be paid in the first quarter of 2017 will
correspond to 15% of 2016s consolidated net income as of September 30, 2016. Additionally, our Board of Directors will propose a definitive dividend payout equal to 50% of the annual consolidated net income for fiscal year 2016. Dividend
payments will be subject to net profits obtained in each period, as well as to expectations of future profit levels and other conditions that may exist at the time of such dividend declaration. The fulfillment of the aforementioned dividend policy
will depend on the 2016 consolidated net income. The proposed dividend policy is subject to our Board of Directors right to change the amount and timing of the dividends under the circumstances at the time of the payment. The payment of
dividends for fiscal year 2015 will be based on the Enersis Américas annual consolidated net income filed with the SVS. For further details, see Item 3. Key Information  A. Selected Financial Data.

The payments of dividends are subject to legal restrictions, such as legal reserve requirements, capital and retained earnings criteria, and
other contractual restrictions such as the non-default on credit agreements. However, these legal restrictions will not affect our ability or any of our combined entities to pay dividends. (See Item 5. Operating and Financial Review and
Prospects  B. Liquidity and Capital Resources for further detail on our debt instruments).

Stockholders set dividend policies
at each subsidiary and affiliate. Dividends will be paid to shareholders of record as of midnight of the fifth business day prior to the payment date. Holders of ADS on the applicable record dates will be entitled to participate in dividends.

Dividends

Dividends have not been paid
to date.

In Chile, our common stock is traded on three stock exchanges since
April 21, 2016: the Santiago Stock Exchange, the Electronic Stock Exchange and the Valparaíso Stock Exchange. The Santiago Stock Exchange, the largest stock exchange in the country was established in 1893 as a private company. Its equity
consists of 42 shares as of the date of this Report. As of December 31, 2015, 223 companies had shares listed on the Santiago Stock Exchange Equities, closed-end funds, fixed-income securities, short-term and money market securities, gold and
U.S. dollars are traded on the Santiago Stock Exchange. The Santiago Stock Exchange also trades U.S. dollar futures and stock index futures. Securities are traded primarily through an open voice auction system; a firm offers system or the daily
auction. Trading through the open voice system occurs on each business day from 9:30 a.m. to 4:00 p.m., during local standard time, and from 9:30 a.m. to 5:00 p.m. during New Yorks daylight savings time (from November to March), which differs
from New York City time by up to two hours, depending on the season. The Santiago Stock Exchange has an electronic trading system called Telepregón, which operates continuously from 9:30 a.m. to 4:00 p.m. during local standard time,
and from 9:00 a.m. to 5:00 p.m. during New Yorks daylight savings time, on each business day. During local standard time, electronic auctions may be conducted four times a day, at 10:30 a.m., 11:30 a.m., 1:30 p.m., and 3:30 p.m. During New
Yorks daylight savings time there is an additional electronic auction at 4:30 p.m. More than 99% of the auctions and transactions take place electronically.

There are two share price indexes on the Santiago Stock Exchange: the General Shares Price Index, or IGPA, and the Selected Shares Price
Index, or IPSA. The IGPA is calculated using the prices of shares that are traded at least 5% of the trading days of a year, with a total annual transactions exceeding UF 10,000 (US$ 0.042 million as of December 31, 2015) and a free float
representing at least 5% of the capital. The IPSA is calculated using the prices of the 40 shares with highest amounts traded on a quarterly basis, and with a market capitalization above US$ 200 million. The shares included in the IPSA and IGPA are
weighted according to the weighted value of the shares traded.

Our common stock trades in the United States in the form of ADSs on the
NYSE by way of when-issued trading since April 21, 2016 under the ticker symbol ENIC WI and regular-way trading since April 27, 2016 under the ticker symbol. Each ADS represents 50 shares of common stock, with the
ADSs in turn evidenced by American Depositary Receipts (ADRs). The ADRs were issued under a Deposit Agreement dated April 26, 2016, among us, Citibank, N.A. acting as Depositary (the Depositary), and the holders and
beneficial owners from time to time of ADRs issued thereunder (the Deposit Agreement). Only persons in whose names ADRs are registered on the books of the Depositary are treated by the Depositary as owners of ADRs.

The NYSE is open for trading Monday through Friday from 9:30 am to 4:00 pm, with the exception of holidays declared by the NYSE in advance. On
the trading floor, the NYSE trades in a continuous auction format, where traders can execute stock transactions on behalf of investors. Specialist brokers act as auctioneers in an open outcry auction market to bring buyers and sellers together and
to manage the actual auction. Customers can also send orders for immediate electronic execution or route orders to the floor for trade in the auction market. The NYSE works with U.S. regulators like the SEC and the Commodity Futures Trading
Commission (CFTC) to coordinate risk management measures in the electronic trading environment through the implementation of mechanisms like circuit breakers and liquidity replenishment points.

Description of Share Capital

Set forth below is certain information concerning our share capital and a brief summary of certain significant provisions of Chilean law and
our by-laws.

General

Shareholders rights in Chilean companies are governed by the companys by-laws (Estatutos), which have the same purpose as
the articles or the certificate of incorporation and the by-laws of a company incorporated in the United States, and by the Chilean Companies Act, Law No. 18,046. In addition, D.L. 3500, or the Pension Funds System Law, which permits the
investment by Chilean pension funds in stock of qualified companies, indirectly affects corporate governance and prescribes certain rights of shareholders. In accordance with the Chilean Companies Act, legal actions by shareholders to enforce their
rights as shareholders of the company must be brought in Chile in arbitration proceedings or, at the option of the plaintiff, before Chilean courts. Members of the Board of Directors, managers, officers and principal executives of the company, or
shareholders that individually own shares with a book value or stock value higher that UF 5,000 (Ch$ 128 million as of December 31, 2015) do not have the option to bring the procedure to the courts. The Chilean securities markets
are principally regulated by the SVS under Securities Market Law (Law No. 18,045), and the Chilean Companies Act. These two laws state the disclosure requirements, restrictions on insider trading and price manipulation, and provide protection
to minority shareholders. The Securities Market Law sets forth requirements for public offerings, stock exchanges and brokers, and outlines disclosure requirements for companies that issue publicly offered securities. The Chilean Companies Act and
the Securities Market Law, both as amended, state rules regarding takeovers, tender offers, transactions with related parties, qualified majorities, share repurchases, directors committee, independent directors, stock options and derivative
actions.

Public Register

As of March 1, 2016, we are a publicly held stock corporation incorporated under the laws of Chile and registered at the Commercial
Registrar (Registro de Comercio del Conservador de Bienes Raíces y Comercio de Santiago). We were constituted by public deed issued on January 8, 2016 by the Santiago Notary Public, Mr. Ivan Torrealba Acevedo, and registered
on January 19, 2016 in the Commercial Registrar (Registro de Comercio del Conservador de Bienes Raíces y Comercio de Santiago) on pages 4288 No. 2570. Our registry in the Securities Registry of the SVS was approved by the SVS
on April 13, 2016, under the entry number 1139. We are also registered with the United States Securities and Exchange Commission under the commission file number 001-37723.

Reporting Requirements Regarding Acquisition or Sale of Shares

Under Article 12 of the Securities Market Law and General Rule 269 of the SVS, certain information regarding transactions in shares of a
publicly held stock corporation or in contracts or securities whose price or results depend on, or are conditioned in whole or in part on the price of such shares, must be reported to the SVS and the Chilean stock exchanges. Since ADSs are deemed to
represent the shares of common stock underlying the ADRs, transactions in ADRs will be subject to these reporting requirements and those established in Circular 1375 of the SVS. Shareholders of publicly held stock corporations are required to report
to the SVS and the Chilean stock exchanges:



| |  |  | any direct or indirect acquisition or sale of shares made by a holder who owns, directly or indirectly, at least 10% of a publicly held stock corporations subscribed capital;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | any direct or indirect acquisition or sale of contracts or securities whose price or results depend on or are conditioned in whole or in part on the price of shares made by a holder who owns, directly or indirectly, at
least 10% of a publicly held stock corporations subscribed capital;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | any direct or indirect acquisition or sale of shares made by a holder who, due to an acquisition of shares of such publicly held stock company, results in the holder acquiring, directly or indirectly, at least 10% of a
publicly held stock companys subscribed capital; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | any direct or indirect acquisition or sale of shares in any amount, made by a director, receiver, principal executive, general manager or manager of a publicly held stock company.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In addition, majority shareholders of a publicly held stock corporation must inform the SVS and the Chilean stock exchanges if such
transactions are entered into with the intention of acquiring control of the company or if they are making a passive financial investment instead.

Under Article 54 of the Securities Market Law and General Rule 104 enacted by the SVS, any person who directly or indirectly intends to take
control of a publicly held stock corporation must disclose this intent to the market at least ten business days in advance of the proposed change of control and, in any event, as soon as the negotiations for the change of control have taken place or
reserved information of the publicly held stock corporation has been provided.

Corporate Objectives and Purposes

Article 4 of our by-laws provides that our corporate objectives and purposes are, among other things, to conduct the exploration, development,
operation, generation, distribution, transformation, or sale of energy in any form, directly or through other companies, as well as to provide engineering-consultancy services related to these objectives, to make loans to related companies,
subsidiaries and affiliates and to participate in the telecommunications business.

Board of Directors

Our Board of Directors initially consisted of seven members who have been initially elected for an interim term at the ESM of the shareholders
of Enersis Américas held on December 18, 2015 to hold office until our first OSM held on April 28, 2016. At the 2016 OSM, the entire Board of Directors consisting of seven members was elected to a three-year term. Following the end
of their term, they may be either re-elected or replaced.

The seven directors elected at the OSM will be the seven individual nominees
who receive the highest number of votes. Each shareholder may vote his shares in favor of one nominee or may apportion his shares among any number of nominees.



96

##### Table of Contents

The effect of these voting provisions is to ensure that a shareholder owning more than 12.5% of
our shares is able to secure the election of a member of the Board. A majority of the Board of Directors, four members, can be secured with more than 50% of the shares.

Normally, the compensation of the directors is established annually at the OSM. Initially, the compensation of the interim Board of Directors
was established at the ESM of the shareholders of Enersis Américas held on December 18, 2015. See Item 6. Directors, Senior Management and Employees B. Compensation.

Future agreements that will be entered into by us with related parties can only be executed when such agreements serve our interest, and their
price, terms and conditions are consistent with prevailing market conditions at the time of their approval and comply with all the requirements and procedures indicated in Article 147 of the Chilean Companies Act.

Certain Powers of the Board of Directors

Our by-laws provide that every agreement or contract that we enter into with our controlling shareholder, our directors or executives, or
their related parties, must be previously approved by two-thirds of the Board of Directors and be included in the Board meetings, and must comply with the provisions of the Chilean Companies Act.

Our by-laws do not contain provisions relating to:



| |  |  | the directors power, in the absence of an independent quorum, to vote on compensation for themselves or any members of their body;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------



| |  |  | borrowing powers exercisable by the directors and how such borrowing powers can be varied;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | retirement or non-retirement of directors under an age limit requirement; or
| | - |  | ----------------------------------------------------------------------------



| |  |  | number of shares, if any, required for directors qualification.
| | - |  | ----------------------------------------------------------------

Certain Provisions Regarding
Shareholder Rights

As of the date of the filing of this Report, our capital is comprised of only one class of shares, all of which
are ordinary shares and have the same rights.

Our by-laws do not contain any provisions relating to:



| |  |  | redemption provisions;
| | - |  | ----------------------



| |  |  | sinking funds; or
| | - |  | -----------------



| |  |  | liability for capital reductions by us.
| | - |  | ---------------------------------------

Under Chilean law, the rights of our stockholders may
only be modified by an amendment to the by-laws that complies with the requirements explained below under Item 10. Additional Information  B. Memorandum and Articles of Association.  Shareholders Meetings and Voting
Rights.

Capitalization

Under
Chilean law, only the shareholders of a company acting at an ESM have the power to authorize a capital increase. When an investor subscribes for shares, these are officially issued and registered under his name, and the subscriber is treated as a
shareholder for all purposes, except receipt of dividends and for return of capital in the event that the shares have been subscribed but not paid for. The subscriber becomes eligible to receive dividends only for the shares that he has actually
paid for or, if the subscriber has paid for only a portion of such shares, the pro rata portion of the dividends declared with respect to such shares unless the companys by-laws provide otherwise. If a subscriber does not fully pay for shares
for which the subscriber has subscribed on or prior to the date agreed upon for payment, notwithstanding the actions intended by the company to collect payment, the company is entitled to auction the shares on the stock exchange where such shares
are traded, for the account and risk of the debtor, the number of shares held by the debtor necessary for the company to pay the outstanding balances and disposal expenses. However, until such shares are sold at auction, the subscriber continues to
hold all the rights of a shareholder, except the right to receive dividends and return of capital. The Chief Executive Officer, or the person replacing him, will reduce in the shareholders register the number of shares in the name of the
debtor shareholder to the number of shares that remain, deducting the shares sold by the company and settling the debt in the amount necessary to cover the result of such disposal after the

corresponding expenses. When there are authorized and issued shares for which full payment has not been made within the period fixed by shareholders at the same ESM at which the subscription was
authorized (which in no case may exceed three years from the date of such meeting), these shall be reduced in the non-subscribed amount until that date. With respect to the shares subscribed and not paid following the term mentioned above, the Board
must proceed to collect payment, unless the shareholders meeting authorizes (by two thirds of the voting shares) a reduction of the companys capital to the amount effectively collected, in which case the capital shall be reduced by force
of law to the amount effectively paid. Once collection actions have been exhausted, the Board should propose to the shareholders meeting the approval by simple majority of the write-off of the outstanding balance and the reduction of capital
to the amount effectively recovered.

As of March 1, 2016, our subscribed and fully paid capital totals Ch$ 2,229 billion and
consists of 49,092,772,762 shares.

Preemptive Rights and Increases of Share Capital

The Chilean Companies Act requires Chilean companies to grant shareholders preemptive rights to purchase a sufficient number of shares to
maintain their existing ownership percentage of such company whenever such company issues new shares.

Under Chilean law, preemptive
rights are exercisable or freely transferable by shareholders during a 30-day period. The options to subscribe for shares in capital increases of the company or of any other securities convertible into shares or that confer future rights over these
shares, should be offered, at least once, to the shareholders pro rata to the shares held registered in their name at midnight on the fifth business day prior to the date of the start of the preemptive rights period. The preemptive rights offering
and the start of the 30-day period for exercising them shall be communicated through the publication of a prominent notice, at least once, in the newspaper that should be used for notifications of shareholders meetings. During such 30-day
period, and for an additional period of up to 30-days immediately following the initial 30-day period, publicly held stock corporations are not permitted to offer any unsubscribed shares to third parties on terms which are more favorable than those
offered to their shareholders. At the end of the second 30-day period, a Chilean publicly held stock corporation is authorized to sell non-subscribed shares to third parties on any terms, provided they are sold on one of the Chilean stock exchanges.

Shareholders Meetings and Voting Rights

An OSM must be held within the first four months following the end of our fiscal year. Our last OSM was held on April 28, 2016. An ESM
may be called by the Board of Directors when deemed appropriate, or when requested by shareholders representing at least 10% of the issued shares with voting rights, or by the SVS. To convene an OSM or an ESM, notice must be given three times in a
newspaper located in our corporate domicile. The newspaper designated by our shareholders is El Mercurio de Santiago. The first notice must be published not less than 15-days and no more than 20-days in advance of the scheduled meeting.
Notice must also be mailed to each shareholder, to the SVS and to the Chilean stock exchanges.

The OSM shall be held on the day stated in
the notice and should remain in session until having exhausted all the matters stated in the notice. However, once constituted, upon the proposal of the chairman or shareholders representing at least 10% of the shares with voting rights, the
majority of the shareholders present may agree to suspend it and to continue it within the same day and place, with no new constitution of the meeting or qualification of powers being necessary, recorded in one set of minutes. Only those
shareholders who were present or represented may attend the recommencement of the meeting with voting rights.

Under Chilean law, a quorum
for a shareholders meeting is established by the presence, in person or by proxy, of shareholders representing at least a majority of the issued shares with voting rights of a company. If a quorum is not present at the first meeting, a
reconvened meeting can take place at which the shareholders present are deemed to constitute a quorum regardless of the percentage of the shares represented. This second meeting must take place within 45-days following the scheduled date for the
first meeting. Shareholders meetings adopt resolutions by the affirmative vote of a majority of those shares present or represented at the meeting. An ESM must be called to take the following actions:



| |  |  | a transformation of the company into a form other than a publicly held stock corporation under the Chilean Companies Act, a merger or split-up of the company;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | an amendment to the term of duration or early dissolution of the company;
| | - |  | -------------------------------------------------------------------------



| |  |  | a change in the companys domicile;
| | - |  | -----------------------------------



| |  |  | a decrease of corporate capital;
| | - |  | --------------------------------



| |  |  | an approval of capital contributions in kind and non-monetary assessments;
| | - |  | --------------------------------------------------------------------------



| |  |  | a modification of the authority reserved to shareholders or limitations on the Board of Directors;
| | - |  | --------------------------------------------------------------------------------------------------

| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | approval or ratification of acts or contracts with related parties.
| | - |  | -------------------------------------------------------------------

Regardless of the quorum
present, the vote required for any of the actions above is at least two-thirds of the outstanding shares with voting rights.

By-law
amendments for the creation of a new class of shares, or an amendment to or an elimination of those classes of shares that already exist, must be approved by at least two-thirds of the outstanding shares of the affected series.

Chilean law does not require a publicly held stock corporation to provide its shareholders the same level and type of information required by
the U.S. securities laws regarding the solicitation of proxies. However, shareholders are entitled to examine the financial statements and corporate books of a publicly held stock corporation within the 15-day period before its scheduled OSM. Under
Chilean law, a notice of a shareholders meeting listing matters to be addressed at the meeting must be mailed at least 15 days prior to the date of such meeting, and, an indication of the way complete copies of the documents that support the matters
submitted for voting can be obtained, which must also be made available to shareholders on our website. In the case of an OSM, our annual report of activities, which includes audited financial statements, must also be made available to shareholders
and published on our website at: www.enersischile.cl.

The Chilean Companies Act provides that, upon the request by the Directors
Committee or by shareholders representing at least 10% of the issued shares with voting rights, a Chilean companys annual report must include, in addition to the materials provided by the Board of Directors to shareholders, such
shareholders comments and proposals in relation to the companys affairs. In accordance with Article 136 of the Chilean Companies Regulation (Reglamento de Sociedades Anónimas), the shareholder(s) holding or representing 10%
or more of the shares issued with voting rights, may:



| |  |  | make comments and proposals relating to the progress of the corporate businesses in the corresponding year, no shareholder being able to make individually or jointly more than one presentation. These observations should
be presented in writing to the company concisely, responsibly and respectfully, and the respective shareholder(s) should state their willingness for these to be included as an appendix to the annual report. The board shall include in an appendix to
the annual report of the year a faithful summary of the pertinent comments and proposals the interested parties had made, provided they are presented during the year or within 30-days after its ending; or
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | make comments and proposals on matters that the board submits for the knowledge or voting of the shareholders. The board shall include a faithful summary of those comments and proposals in all information it sends to
shareholders, provided the shareholders proposal is received at the offices of the company at least 10-days prior to the date of dispatch of the information by the company. The shareholders should present their comments and proposals to the
company, expressing their willingness for these to be included in the appendix to the respective annual report or in information sent to shareholders, as the case may be. The observations referred to in this Article may be made separately by each
shareholder holding 10% or more of the shares issued with voting rights or shareholders who together hold that percentage, who should act as one.

##### Table of Contents

Similarly, the Chilean Companies Act provides that whenever the Board of Directors of a publicly
held stock corporation convenes an OSM and solicits proxies for the meeting, or circulates information supporting its decisions or other similar material, it is obligated to include the pertinent comments and proposals that may have been made by the
Directors Committee or by shareholders owning 10% or more of the shares with voting rights who request that such comments and proposals be so included.

Only shareholders registered as such with us as of midnight on the fifth business day prior to the date of a meeting are entitled to attend
and vote their shares. A shareholder may appoint another individual, who does not need to be a shareholder, as his proxy to attend the meeting and vote on his behalf. Proxies for such representation shall be given for all the shares held by the
owner. The proxy may contain specific instructions to approve, reject, or abstain with respect to any of the matters submitted for voting at the meeting and which were included in the notice. Every shareholder entitled to attend and vote at a
shareholders meeting shall have one vote for every share subscribed.

There are no limitations imposed by Chilean law or our by-laws
on the right of nonresidents or foreigners to hold or vote shares of common stock. However, the registered holder of the shares of common stock represented by ADSs, and evidenced by outstanding ADSs, is the custodian of the depositary currently
Banco Santander Santiago-Chile, or any successor thereto. Accordingly, holders of ADSs are not entitled to receive notice of meetings of shareholders directly or to vote the underlying shares of common stock represented by ADS directly. The Deposit
Agreement contains provisions pursuant to which the depositary has agreed to solicit instructions from registered holders of ADSs as to the exercise of the voting rights pertaining to the shares of common stock represented by the ADSs. Subject to
compliance with the requirements of the Deposit Agreement and receipt of such instructions, the Depositary has agreed to endeavor, insofar as practicable and permitted under Chilean law and the provisions of the by-laws, to vote or cause to be voted
(or grant a discretionary proxy to the Chairman of the Board of Directors or to a person designated by the Chairman of the Board of Directors to vote) the shares of common stock represented by the ADSs in accordance with any such instruction. The
Depositary shall not itself exercise any voting discretion over any shares of common stock underlying ADSs. If no voting instructions are received by the Depositary from a holder of ADSs with respect to the shares of common stock represented by the
ADSs, on or before the date established by the Depositary for such purpose, the shares of common stock represented by the ADS, may be voted in the manner directed by the Chairman of the Board, or by a person designated by the Chairman of the Board,
subject to limitations set forth in the Deposit Agreement.

Dividends and Liquidation Rights

According to the Chilean Companies Act, unless otherwise decided by unanimous vote of its issued shares eligible to vote, all companies must
distribute a cash dividend in an amount equal to at least 30% of their combined net income, before amortization and negative goodwill for each year (calculated according to the local accounting rules applicable to us when preparing financial
statements to be submitted to the SVS), unless and except to the extent we have carried forward losses. The law provides that the Board of Directors must agree to the dividend policy and inform such policy to the shareholders at the OSM.

Any dividend in excess of 30% of net income may be paid, at the election of the shareholders, in cash, or in our shares, or in shares of
publicly held corporations owned by us. Shareholders who do not expressly elect to receive a dividend other than in cash are legally presumed to have decided to receive the dividend in cash.

Dividends, which are declared but not paid within the appropriate time period set forth in the Chilean Companies Act (as to minimum dividends,
30-days after declaration; as to additional dividends, the date set for payment at the time of declaration), are adjusted to reflect the change in the value of UF, from the date set for payment to the date such dividends are actually paid. Such
dividends also accrue interest at the then-prevailing rate for UF-denominated deposits during such period. The right to receive a dividend lapses if it is not claimed within five years from the date such dividend is payable. Payments not collected
in such period are transferred to the volunteer fire department.

In the event of our liquidation, the shareholders would participate in
the assets available in proportion to the number of paid-in shares held by them, after payment to all creditors.

Approval of Financial Statements

The Board of Directors is required to submit our combined financial statements to the shareholders annually for their approval. If
the shareholders by a vote of a majority of shares present (in person or by proxy) at the shareholders meeting reject the financial statements, the Board of Directors must submit new financial statements no later than 60-days from the date of
such meeting. If the shareholders reject the new financial statements, the entire Board of Directors is deemed removed from office and a new board is elected at the same meeting. Directors who individually approved such financial statements are
disqualified for reelection for the following period.

Change of Control

The Capital Markets Law establishes a comprehensive regulation related to tender offers. The law defines a tender offer as the offer to
purchase shares of companies which publicly offer their shares or securities convertibles into shares and which offer is made to shareholders to purchase their shares under conditions which allow the bidder to reach a certain percentage of ownership
of the company within a fixed period of time. These provisions apply to both voluntary and hostile tender offers.

Acquisition of Shares

No provision in our by-laws discriminates against any existing or prospective holder of shares as a result of such shareholder owning a
substantial number of shares. However, no person may directly or indirectly own more than 65% of the outstanding shares of our stock. The foregoing restriction does not apply to the depositary as record owner of shares represented by ADRs, but it
does apply to each beneficial ADS holder. Additionally, our by-laws will prohibit any shareholder from exercising voting power with respect to more than 65% of the common stock owned by such shareholder or on behalf of others representing more than
65% of the outstanding issued shares with voting rights.

Right of Dissenting Shareholders to Tender Their Shares

The Chilean Companies Act provides that upon the adoption of any of the resolutions enumerated below at a meeting of shareholders, dissenting
shareholders acquire the right to withdraw from the company and to compel the company to repurchase their shares, subject to the fulfillment of certain terms and conditions. In order to exercise such withdrawal rights, holders of ADRs must first
withdraw the shares represented by their ADRs pursuant to the terms of the Deposit Agreement.

Dissenting shareholders are
defined as those who at a shareholders meeting vote against a resolution that results in the withdrawal right, or who if absent from such meeting, state in writing their opposition to the respective resolution, within the 30-days following the
shareholders meeting. Shareholders present or represented at the meeting and who abstain in exercising their voting rights shall not be considered as dissenting. The right to withdraw should be exercised for all the shares that the dissenting
shareholder had registered in their name on the date on which the right is determined to participate in the meeting at which the resolution is adopted that motivates the withdrawal and which remains on the date on which their intention to withdraw
is communicated to the company.

The price paid to a dissenting shareholder of a publicly held stock corporation whose shares are quoted
and actively traded on one of the Chilean stock exchanges is the weighted average of the sales prices for the shares as reported on the Chilean stock exchanges on which the shares are quoted for the two-month period between the ninetieth and the
thirtieth day before the shareholders meeting giving rise to the withdrawal right. If, because of the volume, frequency, number and diversity of the buyers and sellers, the SVS determines that the shares are not actively traded on a stock
exchange, the price paid to the dissenting shareholder shall be the book value. Book value for this purpose shall equal paid capital plus reserves and profits, less losses, divided by the total number of subscribed shares, whether entirely or
partially paid. For the purpose of making this calculation, the last combined statements of financial position is used, as adjusted to reflect inflation up to the date of the shareholders meeting which gave rise to the withdrawal right.

Article 126 of the Chilean Companies Act Regulations establishes that in cases where the right to withdraw arises, the company shall be
obliged to inform the shareholders of this situation, the value per share that will be paid to shareholders exercising their right to withdraw and the term for exercising it. Such information should be given to shareholders at the same meeting at
which the resolutions are adopted giving rise to the right of withdrawal, prior to its voting. A special communication should be given to the shareholders with rights, within two days following the date on which the rights to withdraw are born. In
the case of publicly held companies, such information shall be communicated by a prominent notice in a newspaper with a wide national circulation and on its website, plus a written communication addressed to the shareholders with rights at the
address they have registered with the company. The notice of the shareholders meeting that should pronounce on a matter that could originate withdrawal rights should mention this circumstance.

The resolutions that result in a shareholders right to withdraw include, among others, the following:



| |  |  | the transformation of the company into an entity which is not a publicly held stock corporation governed by Chilean Companies Act;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------



| |  |  | the merger of the company with another company;
| | - |  | -----------------------------------------------



| |  |  | disposition of 50% or more of the assets of the company, whether it includes disposition of liabilities or not, as well as the approval or the amendment of the business plan which contemplates the disposition of assets
in an amount greater than such percentage;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | the disposition of 50% or more of the assets of a combined entity, as long as such combined entity represents at least 20% of the assets of the company, as well as any disposition of its shares that results in the
parent company losing its position of controller;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | issue of guarantees for third parties liabilities which exceed 50% of the assets (if the third party is a combined entity of the company, the approval of the Board of Directors is sufficient);
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the creation of preferential rights for a class of shares or an amendment to the existing ones. In this case the right to withdraw only accrues to the dissenting shareholders of the class or classes of shares adversely
affected;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | certain remedies for the nullification of the corporate by-laws; and

| |  |  | such other causes as may be established by the law or by the companys by-laws.

Investments by AFPs

The Pension Funds System Law permits AFPs to invest their funds in companies that are subject to Title XII and, subject to
greater restrictions than other companies. The determination of which stocks may be purchased by AFPs is made by the Risk Classification Committee. The Risk Classification Committee establishes investment guidelines and is empowered to approve or
disapprove those companies that are eligible for AFP investments. We are a Title XII company and are approved by the Risk Classification Committee.

Title XII companies are required to have by-laws that:



| |  |  | limit the ownership of any shareholder to a specified maximum percentage;
| | - |  | -------------------------------------------------------------------------



| |  |  | require that certain actions be taken only at a meeting of the shareholders; and
| | - |  | --------------------------------------------------------------------------------



| |  |  | give the shareholders the right to approve certain investment and financing policies.

Registrations and
Transfers

Shares issued by us are registered with an administrative agent, which isDCV Registros S.A. This entity is also
responsible for our shareholders registry. In case of jointly-owned shares, an attorney-in-fact must be appointed to represent the joint owners in dealing with us.

Appropriate registration of a foreign investment in Chile permits the investor access to the Formal Exchange Market. Foreign investments can be registered with the Foreign Investment Committee under D.L. 600 of 1974 or can be registered with
the Central Bank of Chile under the Central Bank Act, Law 18840 of October 1989.



|a) | Chapter XIV

The following is a summary of certain provisions of Chapter XIV
that are applicable to all existing shareholders (and ADS holders). This summary does not purport to be complete and is qualified in its entirety by reference to Chapter XIV. Chapter XIV regulates the following type of investments:
credits, deposits, investments and equity contributions. A Chapter XIV investor may at any time repatriate an investment made in us upon sale of our shares, and the profits derived therefrom, with no monetary ceiling, subject to the then
effective regulations, which must be reported to the Central Bank of Chile.

Except for compliance with tax regulations and some reporting
requirements, currently there are no rules in Chile affecting repatriation rights, except that the remittance of foreign currency must be made through a Formal Exchange Market entity. However, the Central Bank of Chile has the authority to change
such rules and impose exchange controls.

Chilean Tax Considerations

The
following discussion summarizes material Chilean income and withholding tax consequences to foreign holders arising from the ownership and disposition of shares and ADSs and, to the extent any are issued, rights and ADS rights. The summary that
follows does not purport to be a comprehensive description of all of the tax considerations that may be relevant to a decision to purchase, own or dispose of shares or ADSs and rights or ADS rights, if any, and does not purport to deal with the tax
consequences applicable to all categories of investors, some of which may be subject to special rules. Holders of shares and ADSs are advised to consult their own tax advisors concerning the Chilean and other tax consequences of the ownership of
shares or ADSs.

The summary that follows is based on Chilean law, in effect on the date hereof, and is subject to any changes in these or
other laws occurring after such date, possibly with retroactive effect. Under Chilean law, provisions contained in statutes such as tax rates applicable to foreign investors, the computation of taxable income for Chilean purposes and the manner in
which Chilean taxes are imposed and collected may be amended only by another law. In addition, the Chilean tax authorities enact rulings and regulations of either general or specific application and interpret the provisions of the Chilean Income Tax
Law. Chilean tax may not be assessed retroactively against taxpayers who act in good faith relying on such rulings, regulations and interpretations, but Chilean tax authorities may change their rulings, regulations and interpretations in the future.
The discussion that follows is also based, in part, on representations of the depositary, and assumes that each obligation in the Deposit Agreement and any related agreements will be performed in accordance with its terms. As of this date, there is
currently no applicable income tax treaty in effect between the United States and Chile. However, in 2010 the United States and Chile signed an income tax treaty that will enter into force once the treaty is ratified by both countries. There can be
no assurance that the treaty will be ratified by either country. The following summary assumes that there is no applicable income tax treaty in effect between the United States and Chile.

As used in this Report, the term foreign holder means either:



| |  |  | in the case of an individual holder, a person who is not a resident of Chile; for purposes of Chilean taxation, an individual is resident of Chile if he or she has resided in Chile for more than six months in one
calendar year, or a total of more than six months in two consecutive fiscal years; or
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | in the case of a legal entity holder, an entity that is not organized under the laws of Chile, unless the shares or ADSs are assigned to a branch, agent, representative or permanent establishment of such entity in
Chile.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Taxation of Shares and ADSs

Taxation of Cash Dividends and Property Distributions

General Rule: The following taxation of cash dividends and property distributions applies until 2016. Cash dividends paid with
respect to the shares or ADSs held by a foreign holder will be subject to Chilean withholding tax, which is withheld and paid by the company. As described in the example below, the amount of the Chilean withholding tax is determined by applying a
35% rate to a grossed-up distribution amount (such amount equal to the sum of the actual distribution amount and the correlative Chilean corporate income tax paid by the issuer), and then subtracting as a credit such Chilean corporate
income tax paid by the issuer. From 2004 through 2010, the Chilean corporate income tax rate was 17% and from 2011 until 2014, the rate was 20%.

In September 2014, a tax reform was enacted (Law 20,780) which, among other topics, progressively increased the corporate income tax
(CIT). The CIT rate will be adjusted as follows: in 2014 it increased from 20% to 21%; in 2015 it increased to 22.5%; in 2016 it increases to 24%; in 2017, depending on which of the two new alternative systems enacted as part of the 2014
tax reform (discussed below) is chosen, the rate increases to 25% for companies electing the accrued income basis and 25.5% for companies electing the cash basis for shareholders. As of 2018, the CIT rate will remain at 25% for companies that
elected the accrued income basis and will increase to 27% for companies that elected the cash basis for shareholders.

The example below
illustrates the effective Chilean withholding tax burden on a cash dividend received by a foreign holder, assuming a Chilean withholding tax base rate of 35%, an effective Chilean corporate income tax rate of 22.5 % (CIT rate for 2015) and a
distribution of 50% of the net income of the company distributable after payment of the Chilean corporate income tax:

|9    |  | Effective dividend withholding rate : Line 7 / Line 4                 |  |        | 16.13% | 

In general, the effective Chilean dividend withholding tax rate, after giving effect to the credit for the
Chilean corporate income tax paid by the company, can be computed using the following formula:



|                     |  |   |  |                                                              |  | 
|-------------------- |  | - |  | ------------------------------------------------------------ |  | 
|Effective Dividend   |  | = |  | (Withholding tax rate) - (Chilean corporate income tax rate) |  | 
|Withholding Tax Rate |  |   |  | 1 - (Chilean corporate income tax rate)                      |  | 

Using the rates prevailing until 2015, the Effective Dividend Withholding Rate is

(35%-22.5%) / (100%-22.5%) = 16.13%

Dividends are generally assumed to have been paid out of our oldest retained profits for purposes of determining the level of Chilean
corporate income tax that was paid by us. For information as to our retained earnings for tax purposes and the tax credit available on the distribution of such retained earnings, see Note 19 of the Notes to our combined financial statements.

Under Chilean Income Tax Law, dividend distributions made in property are subject to the same Chilean tax rules as cash dividends. Stock
dividends that represent free shares distributed to foreign shareholders as a consequence of a capitalization made on the same corporation are not subject to Chilean taxation.

Exceptions: Despite the aforementioned general rule, there are special circumstances under which a different tax treatment would
apply depending on the source of the income or due to special circumstances existing at the date of the dividend distribution. The most common special cases are briefly described below:

1) Circumstances where there is no CIT credit against the Chilean withholding tax: These cases are when: (i) profits paid
as dividends (following the seniority rule indicated above) exceed a companys taxable income (such dividend distributions in excess of a companys taxable income determined as of December 31 of the distributions year will be
subject to the Chilean withholding tax rate of 35%, without the CIT credit; in relation to the provisional withholding rule applicable on the date of the dividend payment, please see number 3 below); or (ii) the income was not subject to CIT
due to an exemption of the Chilean corporate income tax, in which case the foreign holder will be also subject to the Chilean withholding tax rate of 35% without the CIT credit.

2) Circumstances where dividends have been attributed to income exempted from all the Chilean income taxes: In these cases,
dividends distributed by a company to the foreign holder will not be subject to Chilean withholding tax. Income exempted from Chilean income tax is expressly listed in the Chilean Income Tax Law.

3) Circumstances where dividends are subject to a provisional withholding tax: In the event that on the date of the dividend
distribution there are no earnings on which income tax has been paid and there are no tax-exempt earnings, a 35% Chilean withholding tax with a provisional 22.5% Chilean CIT credit is applicable. This provisional 22.5% Chilean corporate income tax
credit must be confirmed with the information of a companys taxable income as of December 31 of the year in which the dividend was paid. A company can agree with the foreign holders to withhold a higher amount in order to avoid under
withholding of the Chilean withholding tax.

4) Circumstances when it is possible to use certain credits in Chile against
income taxes paid abroad, or foreign tax credit: This occurs when dividends distributed by the Chilean company have income generated by companies domiciled in third countries as their source. If that income was subject to withholding tax
or corporate income tax in those third countries, such income will have a credit or foreign tax credit against corresponding Chilean taxes, which can be proportionally transferred to the shareholders of a Chilean company.

New System in effect starting in 2017

The tax reform released in September 2014 created two alternative mechanisms of shareholder-level income taxation beginning on January 1,
2017: a) accrued income basis (known as attributed-income system in Chile) shareholder taxation and b) cash basis (known as partially-integrated system in Chile and most similar to the current system) shareholder taxation. On February 8, 2016,
Law 20,899 was enacted, which made adjustments to the tax reform released in September 2014. Among other adjustments, Law 20,899 established that taxpayers whose owners (partners or shareholders) are exclusively individual persons may choose to
apply either of the aforementioned systems. The selection should be made before the end of 2016. Once the election is made, it will remain in effect for five years. If no regime is chosen by a taxpayer whose owners are individual persons, the law
states that the default system will be the accrued income basis. For other taxpayers, whose owners are not exclusively individual persons, the cash basis system (partially-integrated system) must be used.

In addition, the aforementioned Law 20,899, expanded the 100% CIT credit against the Chilean shareholder tax to taxpayers who are residents in
countries with which Chile has an effective or signed tax treaty to avoid international double taxation prior to January 1, 2017, even if not in force as of such date. This is currently the status of the treaty signed between Chile and United
States. This temporary rule will be in force from January 1, 2017 through December 31, 2019.

a) Accrued income basis

Shareholders would be taxed in Chile on income attributed to them as of the end of the tax year in which the income is generated,
eliminating the taxable profits fund ledger (FUT in its Spanish acronym). These profits would be taxed at the shareholder level whether or not they are distributed. The underlying CIT paid at the entity level may be used by shareholders
as a credit to reduce the Chilean shareholder tax. Therefore, the combined total company and shareholder Chilean income tax burden remains at 35%. Future distributions are not subject to taxation.

Taxpayers will be taxed on the income of companies in which they have an interest in the year such income is recognized, regardless of whether
actual distributions are made, with the corresponding credit.

|-------------- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------
| Company:     |  | 25% of accrued profits (using the maximum CIT applicable as of 2018).                                                                                              
|               | 
| Shareholder: |  | 35% of accrued profits (whether or not distributions are received, with 100% credit of the CIT paid, resulting in an effective tax rate to the shareholder of 10%).

Total Tax Burden: 35%

Progressive CIT tax rate increase: 21% in 2014, 22.5% in 2015, 24% in 2016 and 25% as of 2017.

Advantages to accrued income tax basis:



| |  |  | CIT Rate of 25% vs. 27% for the cash basis.
| | - |  | -------------------------------------------

| |  |  | Shareholders are granted 100% credit of taxes paid by a company.
| | - |  | ----------------------------------------------------------------

Disadvantages to accrued income tax basis:



| |  |  | Shareholders are taxed on undistributed profits.
| | - |  | ------------------------------------------------

| |  |  | Shareholders of record must pay tax by December 31st (regardless of having received dividends).
| | - |  | -----------------------------------------------------------------------------------------------

| |  |  | Complex management for companies.
| | - |  | ---------------------------------

b) Cash basis

A company pays CIT on its annual result. Foreign and local individual shareholders will only pay in Chile the relevant tax on effective profit distributions
and will be allowed to use the tax paid by the distributing company as credit, with certain limitations. Only 65% of the CIT is creditable against the 35% shareholder-level tax (as opposed to 100% under the current FUT regime and under the accrued
income basis). However, if there is an effective or signed tax treaty with Chile before January 1, 2017 (even if not yet in effect), the CIT is fully creditable against the 35% shareholder tax.

Taxation on sale or exchange of ADSs, outside of Chile

Gains obtained by a foreign holder from the sale or exchange of ADSs outside Chile will not be subject to Chilean taxation.

Taxation on sale or exchange of Shares

The Chilean Income Tax Law includes a tax exemption on capital gains arising from the sale of shares of listed companies traded in the stock
markets. Although there are certain restrictions, in general terms, the amendment provides that in order to qualify for the capital gain exemption: (i) the shares must be of a publicly held stock corporation with a certain minimum level of
trading on a stock exchange; (ii) the sale must be carried out in a Chilean stock exchange, or in a tender offer subject to Chapter XXV of the Chilean Securities Market Law; (iii) the shares which are being sold must have been acquired on
a Chilean stock exchange, or in a tender offer subject to Chapter XXV of the Chilean Securities Market Law, or in an initial public offering (due to the creation of a company or to a capital increase), or due to the exchange of convertible bonds;
and (iv) the shares must have been acquired after April 19, 2001.

If the shares do not qualify for the above exemption, capital
gains on their sale or exchange of shares (as distinguished from sales or exchanges of ADSs representing such shares of common stock) could be subject to two alternative tax regimes: (a) the general tax regime, with a 22.5% Chilean corporate
income tax and a 35% Chilean withholding tax, the former being creditable against the latter; or (b) a 22.5% Chilean corporate income tax as sole tax regime, when all the following circumstances are met: (i) the sale is made between
unrelated parties, (ii) the sale of shares is not a recurrent or habitual activity for the seller and (iii) at least one year has elapsed between the acquisition and the sale of the shares.

The date of acquisition of the ADSs is considered to be the date of acquisition of the shares for which the ADSs are exchanged.

Taxation of Rights and ADS Rights

For Chilean tax purposes and to the extent we issue any rights or ADS rights, the receipt of rights or ADS rights by a foreign holder of
shares or ADSs pursuant to a rights offering is a nontaxable event. In addition, there are no Chilean income tax consequences to foreign holders upon the exercise or the lapse of the rights or the ADS rights.

Any gain on the sale, exchange or transfer of any ADS rights by a foreign holder is not subject to taxes in Chile.

Any gain on the sale, exchange or transfer of the rights by a foreign holder is subject to a 35% Chilean withholding tax.

Currently, there are no rights that are outstanding.

Other Chilean Taxes

There is no gift, inheritance or succession tax applicable to the ownership, transfer or disposition of ADSs by foreign holders, but such
taxes will generally apply to the transfer at death or by gift of the shares by a foreign holder. There is no Chilean stamp, issue, registration or similar taxes or duties payable by holders of shares or ADSs.

Material U.S. Income Tax Considerations

This discussion is based on the Internal Revenue Code of 1986, as amended (the Code), administrative pronouncements, judicial
decisions and final, temporary and proposed Treasury regulations, all as of the date hereof. These authorities are subject to change, possibly with retroactive effect. This discussion assumes that the depositarys activities are clearly and
appropriately defined so as to ensure that the tax treatment of ADSs will be identical to the tax treatment of the underlying shares.

The
following are the material U.S. federal income tax consequences to U.S. Holders (as defined herein) of receiving, owning, and disposing of shares or ADSs, but it does not purport to be a comprehensive description of all of the tax considerations
that may be relevant to a particular persons decision to hold such securities and is based on the assumption stated above under Chilean Tax Considerations that there is no applicable income tax treaty in effect between the United
States and Chile. The discussion applies only if the beneficial owner holds shares or ADSs as capital assets for U.S. federal income tax purposes and it does not describe all of the tax consequences that may be relevant in light of the beneficial
owners particular circumstances. For instance, it does not describe all the tax consequences that may be relevant to:



| |  |  | certain financial institutions;
| | - |  | -------------------------------



| |  |  | insurance companies;
| | - |  | --------------------



| |  |  | dealers and traders in securities who use a mark-to-market method of tax accounting;
| | - |  | ------------------------------------------------------------------------------------



| |  |  | persons holding shares or ADSs as part of a straddle integrated transaction or similar transaction;
| | - |  | -----------------------------------------------------------------------------------------------------



| |  |  | persons whose functional currency for U.S. federal income tax purposes is not the U.S. dollar;
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | partnerships or other entities classified as partnerships for U.S. federal income tax purposes;
| | - |  | -----------------------------------------------------------------------------------------------



| |  |  | persons liable for the alternative minimum tax;
| | - |  | -----------------------------------------------



| |  |  | tax-exempt organizations;
| | - |  | -------------------------



| |  |  | persons holding shares or ADSs that own or are deemed to own ten percent or more of our stock; or
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | persons holding shares or ADSs in connection with a trade or business conducted outside of the United States.
| | - |  | -------------------------------------------------------------------------------------------------------------

If an entity classified as a partnership for U.S. federal income tax purposes holds shares or ADSs, the U.S. federal income tax treatment of a
partner will generally depend on the status of the partner and upon the activities of the partnership. Partnerships holding shares or ADSs and partners in such partnerships should consult their tax advisors as to the particular U.S. federal income
tax consequences of holding and disposing of the shares or ADSs.

You will be a U.S. Holder for purposes of this discussion if
you become a beneficial owner of our shares or ADSs and if you are, for U.S. federal income tax purposes:



| |  |  | a citizen or individual resident of the United States; or
| | - |  | ---------------------------------------------------------



| |  |  | a corporation, or other entity taxable as a corporation, created or organized in or under the laws of the United States or any political subdivision thereof; or
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | an estate, the income of which is subject to U.S. federal income taxation regardless of its source; or
| | - |  | ------------------------------------------------------------------------------------------------------



| |  |  | a trust (i) that validly elects to be treated as a U.S. person for U.S. federal income tax purposes or (ii) if (A) a court within the United States is able to exercise primary supervision over the
administration of the trust and (B) one or more U.S. persons have the authority to control all substantial decisions of the trust.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In general, if a beneficial owner owns ADSs, such owner will be treated as the owner of the shares represented by those ADSs for U.S. federal
income tax purposes. Accordingly, no gain or loss will be recognized if a beneficial owner exchanges ADSs for the underlying shares represented by those ADSs.

The U.S. Treasury has expressed concerns that parties to whom ADSs are released before shares are delivered to the depositary (pre-release) or
intermediaries in the chain of ownership between beneficial owners and the issuer of the security underlying the ADSs

may be taking actions that are inconsistent with the claiming of foreign tax credits for beneficial owners of depositary shares. Such actions would also be inconsistent with the claiming of the
reduced tax rate, described below, applicable to dividends received by certain non-corporate beneficial owners. Accordingly, the analysis of the creditability of Chilean taxes, and the availability of the reduced tax rate for dividends received by
certain non-corporate holders, each described below, could be affected by actions taken by such parties or intermediaries.

This
discussion assumes that we will not be a passive foreign investment company, as described below.

Beneficial owners should consult their
tax advisors with respect to their particular tax consequences of owning or disposing of shares or ADSs, including the applicability and effect of state, local, non-U.S. and other tax laws and the possibility of changes in tax laws.

Taxation of Distributions

The following discussion is based on the current regime for taxation of cash dividends and distributions applicable in Chile until 2016. For
2017 and later, the U.S. federal income tax treatment will depend on which of the two regimes we elect to adopt. See  Chilean Tax Considerations  Taxation of shares and ADSs  Taxation of Cash Dividends and Property
Distributions above.

Distributions paid on shares or ADSs other than certain pro rata distributions of shares of common stock will
be treated as dividends taxable as ordinary income to the extent paid out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles). Because we do not maintain calculations of our earnings and
profits under U.S. federal income tax principles, it is expected that distributions generally will be reported as dividends.

If a
beneficial owner is a U.S. Holder, subject to applicable limitations and the discussion above regarding concerns expressed by the U.S. Treasury, dividends paid by qualified foreign corporations to the beneficial owner that is not a corporation are
taxable at a maximum rate of 20%. A foreign company is treated as a qualified foreign corporation with respect to dividends paid on stock that is readily tradable on an established securities market in the United States, such as the New York Stock
Exchange where our ADSs are traded. Beneficial owners should consult their tax advisors to determine whether the favorable rate will apply to dividends they receive and whether they are subject to any special rules that limit their ability to be
taxed at this favorable rate.

The amount of a dividend will include the net amount withheld by us in respect of Chilean withholding taxes
on the distribution. The amount of the dividend will be treated as foreign-source dividend income to a beneficial owner and will not be eligible for the dividends-received deduction generally allowed to U.S. corporations under the Code. Dividends
will be included in a beneficial owners income on the date of the beneficial owners, or in the case of ADSs, the Depositarys receipt of the dividend. The amount of any dividend paid in Chilean pesos will be a U.S. dollar amount
calculated by reference to the exchange rate for converting Chilean pesos into U.S. dollars in effect on the date of such receipt regardless of whether the payment is in fact converted into U.S. dollars. If the dividend is converted into U.S.
dollars on the date of receipt, a beneficial owner generally should not be required to recognize foreign currency gain or loss in respect of the dividend income. A beneficial owner may have foreign currency gain or loss if the dividend is converted
into U.S. dollars on a date after the date of receipt.

Subject to applicable limitations that may vary depending upon a beneficial
owners circumstances and subject to the discussion above regarding concerns expressed by the U.S. Treasury, the net amount of Chilean withholding tax (after reduction for the credit for Chilean corporate income tax, as discussed above under
 Chilean Tax Considerations  Taxation of Shares and ADSs  Taxation of Cash Dividends and Property Distributions above) withheld from dividends on shares or ADSs will be creditable against a beneficial owners U.S.
federal income tax liability. The rules governing foreign tax credits are complex and, therefore, a beneficial owner should consult the beneficial owners tax advisor regarding the availability of foreign tax credits in the beneficial
owners particular circumstances. Instead of claiming a credit, a beneficial owner may, at the beneficial owners election, deduct such Chilean taxes in computing the beneficial owners taxable income, subject to generally applicable
limitations under U.S. law. An election to deduct foreign taxes instead of claiming foreign tax credits applies to all taxes paid or accrued in the taxable year to foreign countries and possessions of the United States.

Sale or Other Disposition of Shares or ADSs

If a beneficial owner is a U.S. Holder, for U.S. federal income tax purposes, the gain or loss a beneficial owner realizes on the sale or
other disposition of shares or ADSs will be a capital gain or loss, and will be a long-term capital gain or loss if the beneficial holder has held the shares or ADSs for more than one year. The amount of a beneficial owners gain or loss will
equal the difference between the beneficial owners tax basis in the shares or ADSs disposed of and the amount realized on the disposition, in each case as determined in U.S. dollars. Such gain or loss will generally be U.S.-source gain or loss
for foreign tax credit purposes. In addition, certain limitations exist on the deductibility of capital losses by both corporate and individual taxpayers.

##### Table of Contents

In certain circumstances, Chilean taxes may be imposed upon the sale of shares. See 
Chilean Tax Considerations  Taxation of Shares and ADSs. If a Chilean tax is imposed on the sale or disposition of shares, and a beneficial owner that is a U.S. Holder does not receive significant foreign source income from other
sources, such beneficial owner may not be able to credit such Chilean tax against the beneficial owners U.S. federal income tax liability.

Passive Foreign Investment Company Rules

We believe that we will not be a passive foreign investment company (PFIC) for U.S. federal income tax purposes for
our 2016 taxable year or for the foreseeable future. However, because PFIC status depends upon the composition of a companys income and assets and the market value of its assets from time to time, and because it is unclear whether certain
types of our income constitute passive income for PFIC purposes, there can be no assurance that we will not be considered a PFIC for any taxable year. If we were to become a PFIC for any taxable year during which a beneficial owner held shares or
ADSs, certain adverse consequences could apply to the beneficial owner, including the imposition of higher amounts of tax than would otherwise apply, and additional filing requirements. Beneficial owners should consult their tax advisors regarding
the consequences to them if we were a PFIC, as well as the availability and advisability of making any election that might mitigate the adverse consequences of PFIC status.

Information Reporting and Backup Withholding

Payments of dividends and sales proceeds that are made within the United States or through certain U.S.-related financial intermediaries
generally are subject to information reporting and to backup withholding unless (i) the beneficial owner is an exempt recipient or (ii) in the case of backup withholding, the beneficial owner provides a correct taxpayer identification
number and certifies that the beneficial owner is not subject to backup withholding.

The amount of any backup withholding from a payment
to a beneficial owner will be allowed as a credit against the beneficial owners U.S. federal income tax liability and may entitle the beneficial owner to a refund, provided that the required information is furnished in a timely fashion to the
Internal Revenue Service.

Medicare Contribution Tax

Legislation enacted in 2010 generally imposes a tax of 3.8% on the net investment income of certain individuals, trusts and
estates. Among other items, net investment income generally includes gross income from dividends and net gain attributable to the disposition of certain property, like the shares or ADSs, less certain deductions. A beneficial owner should consult
the beneficial owners tax advisor regarding the possible application of this legislation in the beneficial owners particular circumstances.

Beneficial owners should consult their tax advisors with respect to the particular consequences to them of receiving, owning or disposing of shares or
ADSs.

|Item 11. | Quantitative and Qualitative Disclosures About Market Risk
|-------- | ----------------------------------------------------------

We are exposed to risks
arising from changes in commodity prices, interest rates and foreign exchange rates, which affect the generation and distribution business in Chile. We also monitor and manage risks of Endesa Chile in coordination with Endesa Chile. Our Board of
Directors approves risk management policies at all levels.

Commodity Price Risk

In our electricity generation business, we are exposed to market risks arising from the price volatility of electricity, natural gas, diesel
oil, and coal. We seek to ensure our fuel supply by securing long-term contracts with our suppliers for periods that are expected to match the lifetime of our generation assets. These contracts generally have provisions that allow us to purchase
natural gas with a pricing formula that combines Henry Hub natural gas and Brent diesel oil at market prices prevailing at the time the purchase occurs. As of December 31, 2015 we held contracts classified as derivative financial instruments
related to diesel oil (133,058 barrels of Brent diesel oil). As of December 31, 2014 we held contracts classified as financial instruments related to natural gas and diesel oil (350,000 MMBTU of Henry Hub and 266,000 barrels of Brent diesel
oil).

In our coal-burning power plants the dispatch or bidding mechanism allows the thermal power plants to cover their operational
costs. However, under certain circumstances, fuel price fluctuations might affect marginal costs. We transfer commodity prices variations to contracted sale prices according to indexing formulas. Due to the drought conditions in the past several
years in Chile and the price volatility of coal, we hedged this risk with commodity instruments available in the international markets. As of December 31, 2015 and 2014, we did not hold any contracts classified as either derivative financial
instruments or financial instruments related either to coal or petroleum based liquid fuel.

Additionally, through adequate commercial
risk mitigation policies, and a hydro-thermal power plant mix, we seek to naturally protect our operating income from electricity price volatility. As of December 31, 2015 and 2014, we did not hold electricity price-sensitive instruments.

We are continually analyzing strategies to hedge commodity price risk, like transferring commodity price variations to the customers
contract prices and/or permanently adjusting commodity indexed price formulas for new Power Purchase Agreements (PPAs) according to our exposure and/or analyzing ways to mitigate risk through hydrological insurance in dry years. In the
future we may use price-sensitive instruments.

Interest Rate Risk

At December 31, 2015 and 2014, an 8% in both years of our outstanding debt obligations were subject to variable interest rates.

We manage interest rate risk by maintaining a mixture of both variable and fixed rate debt, according to the policy approved by the Board of
Directors. Additionally, we manage interest rate risk through the use of interest rate derivatives. The above percentages include the effect of interest rate derivatives (swaps or collars) that hedge part of our debt.

As of December 31, 2015 and 2014 we did not hold derivatives to hedge our interest rate risk.

Foreign Currency Risk

Our policy seeks
to maintain a balance between the currency in which cash flows are indexed and the currency of the debt of each company. Most of our combined entities have access to funding in the same currency as their revenues, therefore reducing the exchange
rate volatility impact. In some cases, we cannot fully benefit from this, and therefore, we try to manage the exposure with financial derivatives such as cross currency swaps or currency forwards, among others. However, this may not always be
possible under reasonable terms due to market conditions.

As of December 31, 2015, the carrying values for financial accounting
purposes and the corresponding fair value of the instruments that hedge our foreign exchange risk were as follows:

Depositary Fees and Charges

Our ADS programs depositary is Citibank, N.A. The Depositary collects fees for delivery and surrender of ADSs directly from
investors depositing shares or surrendering ADSs for the purpose of withdrawal or from intermediaries acting for them. The Depositary fees payable for cash distributions are deducted from the cash being distributed. In the case of distributions
other than cash, the Depositary will invoice the applicable ADS record date holders and such fees may be deducted from distributions. The Depositary may generally refuse to provide the requested services until its fees for those services are paid.
Under the terms of the Deposit Agreement, an ADS holder may have to pay the following service fees to the Depositary:

Not applicable.



|Item 14. | Material Modifications to the Rights of Security Holders and Use of Proceeds
|-------- | ----------------------------------------------------------------------------

Not

|Item 15. | Controls and Procedures
|-------- | -----------------------

(a)   Disclosure Controls and Procedures

We carried out an evaluation under the supervision and with the participation of our senior management, including the Chief Executive Officer
and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) for the year ended December 31, 2015.

There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human
error, and the circumvention or overriding of the controls and procedures. Accordingly, our disclosure controls and procedures are designed to provide reasonable assurance of achieving their control objectives.

Based upon our evaluation, the Chief Executive Officer and the Chief Financial Officer concluded that the disclosure controls and procedures
are effective in providing reasonable assurance that information required to be disclosed in the reports we file and submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the applicable
rules and forms, and that it is gathered and communicated to our management, including the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives, and our principal executive
officer and principal financial officer have concluded that our disclosure controls and procedures are effective at that reasonable assurance level.

(b)   Managements Annual Report on Internal Control Over Financial Reporting

This annual report does not include a report of managements assessment regarding internal control over financial reporting due to a
transition period established by rules of the Securities and Exchange Commission for newly public companies.

Moreover we are working to
implement an internal control over financial reporting model for the year 2016 which applies an end-to-end approach. The assessment will be based on criteria established in Internal Control  Integrated Framework issued by the
Committee of Sponsoring Organizations of the Treadway Commission (COSO 2013 framework).

(c)   Attestation Report

This annual report does not include an attestation report of the companys registered public accounting firm due to a transition period
established by rules of the Securities and Exchange Commission for newly public companies.

(d)   Changes in internal control

There were no changes in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d)
or Rule 15d-15(d) under the Exchange Act that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting model.

|Item 16A. | Audit Committee Financial Expert
|--------- | --------------------------------

As of March, 2016, the Directors Committee
(which performs the functions of the Audit Committee) financial expert was Mr. Fernan Gazmuri P., as determined by the Board of Directors. Mr. Gazmuri is an independent member of the Directors Committee pursuant to the requirement of
both Chilean law and NYSE corporate governance rules.



|Item 16B. | Code of Ethics
|--------- | --------------

Our standards of ethical conduct are governed by means of the following
four corporate rulings or policies: the Code of Ethics, the Zero Tolerance Anti-Corruption Plan (the ZTAC Plan), the Human Rights Policy and the Manual for the Management of Information of Interest to the Market (the Manual).

The Charter Governing Executives was adopted by the Board of Directors and is applicable to all executives contractually related to us or
our controlled subsidiaries in which we are the majority shareholder, including the Chief Executive Officer, the Chief Financial Officer and other senior officers of the Company. The objective of this set of rules is to establish standards for the
governance of our managements actions, the behavior of management with respect to the principles governing their actions and the limitations and incompatibilities involved, all within our vision, mission and values. Likewise, the Employee Code
of Conduct explains our principles and ethical values, establishes the rules governing our contact with customers and suppliers, and establishes the principles that should be followed by employees, including ethical conduct, professionalism and
confidentiality. Both documents also impose limitations on the activities that our executives and other employees may undertake outside the scope of their employment with us.

The Manual, adopted by our Board of Directors, addresses the following issues: applicable standards and blackout periods regarding the
information in connection with transactions of our securities or those of our affiliates, entered into by directors, management, principal executives, employees and other related parties; the existence of mechanisms for the continuous disclosure of
information that is of interest to the market; and mechanisms that provide protection for confidential information.

In addition to the
corporate governance rules described above, our Board adopted the Code of Ethics, the ZTAC Plan and the Human Rights Policy. The Code of Ethics is based on general principles such as impartiality, honesty, integrity and other values of similar
importance, which are translated into detailed behavioral criteria. The ZTAC Plan reinforces the principles included in the Code of Ethics, but with a special emphasis in avoiding corruption in the form of bribes, preferential treatment, and other
similar matters. The Human Rights Policy incorporates and adapts the general principles acknowledged by the United Nations in matter of human rights into the corporate reality.

Prior to the consummation of the Spin-Off on

Report of Independent Registered Public Accounting Firm

To Shareholders and Directors of

Enersis Chile S.A.

We have audited the accompanying combined statements of financial position of Enersis Chile S.A. (the Combined Group as described in Note 2 to the
combined financial statements) as of December 31, 2015 and 2014, and the related combined statements of comprehensive income, shareholders equity and cash flows for each of the three years in the period ended December 31, 2015. These
financial statements are the responsibility of the Companys management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the Combined Groups internal control over financial reporting. Our
audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Combined
Groups internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting
principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the combined financial position of Enersis Chile S.A. at
December 31, 2015 and 2014, and the combined results of their operations and their cash flows for each of the three years in the period ended December 31, 2015, in conformity with International Financial Reporting Standards (IFRS), as
issued by the International Accounting Standards Board.

ENERSIS CHILE

COMBINED FINANCIAL STATEMENTS AS OF DECEMBER 31, 2015 AND 2014

(In thousands of Chilean pesos)





|1. | BACKGROUND.
|-- | -----------

On April 28, 2015, Enersis S.A. (Enersis) informed the Superintendency of
Securities and Insurance (hereinafter SVS) through a significant event, that the Board of Directors of the company decided by unanimous vote to initiate an analysis of a corporate reorganization (reorganization) aimed at the
separation of the activities of generation and distribution of electricity in Chile from activities outside of Chile. The objective of this would be to resolve certain duplications and redundancies that arise from Enersis complex corporate
structure today and generate value for all its shareholders while, maintaining its inclusion in the Enel S.p.A. group.

On July 27, 2015, pursuant to
the provisions of Articles 9 and 10 of the Securities Market Law No. 18,045 and the provisions of General Norm No. 30 of the SVS, Enersis informed the SVS, by means of a significant event, that the Board of Directors of the company had
decided unanimously that if the separation of power generation and distribution activities in Chile from the rest of the activities of the Enersis group outside of Chile were approved, the reorganization would be carried out through certain
corporate transactions.

On November 10, 2015, an extraordinary meeting of the Board of Directors of Enersis S.A. was held, which agreed to summon an
Extraordinary Shareholders Meeting on December 18, 2015, in order to approve the corporate reorganization and other related topics.

At the
Extraordinary Shareholders Meeting of Enersis held on December 18, 2015, the shareholders approved the spin-off of Enersis into two companies (the Spin-Off). As a result of this Spin-Off will be created Enersis Chile S.A.
(Enersis Chile), a new publicly held company, which will be governed under Chapter XII of D.L. 3,500 and to which were allocated the shareholdings and other associated assets and liabilities of Enersis in Chile, including the ownership
interests in Endesa Chile and Chilectra Chile, already spun-off. All of Enersis shareholders will participate in Enersis Chile in the same proportion that they had in the Enersis capital, with a number of shares equal to what they had in
Enersis (ratio 1:1); remaining in the demerged company (Enersis) all the respective business currently outside of Chile, including its ownership interests in the new entities resulting from the spin-offs of Chilectra and Endesa Chile,
and all the assets and liabilities and administrative authorizations in Chile not expressly allocated to Enersis Chile in the Spin-Off.

As part of the
Spin-Off, it was agreed to reduce the capital of Enersis as a consequence of the Spin-Off from Ch$5,804,447,986,000 divided into 49,092,772,762 registered common shares of a single series and no par value, to the new amount of Ch$3,575,339,011,549
divided into 49,092,772,762 registered common shares of a single series and no par value. Additionally, it was also agreed to (i) establish the capital of Enersis Chile at Ch$2,229,108,974,451 corresponding to the amount by which the capital of
Enersis has been decreased, divided into 49,092,772,762 registered common shares, all of the same series and no par value, and (ii) distribute the companys equity interest between Enersis and Enersis Chile, by allocating assets and
liabilities as indicated by the aforementioned meeting, to Enersis Chile (See Note 2.1).

Likewise, the by-laws of Enersis were approved as a result of
the Spin-Off as follows: (i) its corporate name was changed to Enersis Américas S.A.; and (ii) it corporate purpose was extended to include loans to related companies.

Meanwhile, the by-laws of Enersis Chile were approved, which, as of its effectiveness, shall be subject, in an anticipated and voluntarily manner, to the
norms set forth in Article 50 Bis of the Chilean Companies Law related to the election of independent directors and the creation of the Directors Committee.

Finally, on January 29, 2016, in compliance with the agreement reached at the Extraordinary Shareholders Meeting of Enersis held on
December 18, 2015 (hereinafter Meeting), the Board of Directors of Enersis S.A. acknowledges that the condition precedent regarding the spin-off of Enersis has been met, and accordingly has also arranged to grant the public deed
that declares the completion of the condition precedent, entitled Public Deed of Compliance of the Condition of the Spin-Off of Enersis, effective on the same date. Consequently, and as agreed at the Meeting, the Enersis Spin-Off
became effective on Tuesday, March 1, 2016, whereupon the new corporation, Enersis Chile S.A. began its existence and the approved capital decrease and the other amendments to the by-laws of Enersis S.A. were verified, which was renamed
Enersis Américas S.A.

##### Table of Contents

Steps to carry out the corporate reorganization of Enersis S.A. that were approved at the Extraordinary
Shareholders Meeting:

a) Related to the preparation of the Combined Financial Statements



| |  | Each of the direct and indirect subsidiaries of Enersis, Chilectra S.A. and Empresa Nacional de Electricidad S.A. (Endesa S.A.) would effect spin-offs, resulting in the formation of a new company from the
spin-off by Chilectra S.A. (Chilectra Américas) and a new company from the spin-off by Endesa S.A. (Endesa Américas), which would be allocated equity interests and other assets that both Chilectra S.A. and
Endesa S.A. hold outside of Chile, as well as certain other assets and liabilities related to them. The new companies, Endesa Américas and Chilectra Américas, will be listed and traded on the same markets where Endesa and Chilectra are
traded. In the case of Endesa Américas it will also be governed under Chapter XII of D.L. 3,500 issued on November 4, 1980.
|- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The continuing companies of Endesa S.A. and Chilectra S.A., that would be allocated the businesses conducted in Chile, and are to be called
Empresa Nacional de Electricidad S.A. (Endesa Chile) and Chilectra Chile S.A. (Chilectra Chile) after the spin-offs.



| |  | At the same time, Enersis will be spun-off and, resulting from this spin-off, will form a new company (Enersis Chile), which will hold the equity interests and assets of Enersis in Chile allocated to it,
including equity interests in Chilectra Chile and Endesa Chile (after the spin-off of these companies described above), and certain other assets and liabilities related to them. The new company, Enersis Chile, will be listed and traded on the same
markets were Enersis is traded and will be governed under Chapter XII of D.L. 3,500 issued on November 4, 1980.
|- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Remaining in the continuing entity named Enersis Américas S.A. are the equity interests and corresponding liabilities of Enersis outside
Chile, as well as those held by each of the new companies Chilectra Américas and Endesa Américas, created as a result of the spin-offs of Chilectra Américas and Endesa Américas mentioned above, and
the liabilities related to them.

b) Related to the subsequent processes of the division phase.



| |  | Once the previously mentioned spin-offs are completed, Enersis Américas would absorb by merger Chilectra Américas and Endesa Américas, and would dissolve them
without liquidation, thus grouping all international shares of the Enersis group outside Chile in Enersis Américas. The merger involving Endesa Américas and Chilectra Américas would take place
as soon as legally possible and in accordance with the applicable regulations. On the other hand, Enersis Chile, through its ownership interest in Endesa Chile and Chilectra Chile would carry out the businesses in Chile, which in its case, would
represent a large reduction of its actual organizational structure.
|- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

On April 13, 2016, the Superintendency of Securities and Insurance
has registered Enersis Chile and its shares in its Securities Registry, and has made the respective listings in the Santiago Stock Exchange, the Valparaíso Stock Exchange, the Chile Electronic Stock Exchange and the New York Stock Exchange of
United States of America, all in accordance with the decision made at the Extraordinary Shareholders Meeting of Enersis Américas S.A. held on December 18, 2015. Therefore, the issued shares of Enersis Chile were distributed free of
any payment to the entitled shareholders of Enersis Américas S.A. on April 21, 2016, and began to be traded on that date.

The preparation of
these combined financial statements of Enersis Chile (hereinafter the Company or the Combined Group), do not include effects that could potentially arise as a result of the previously mentioned merger.

These combined financial statements are presented in thousands of Chilean pesos (unless otherwise stated) which is the Companys functional and
presentation currency. Chilean operations with functional currencies other than the Chilean peso are reported in accordance with the accounting policies described in Note 3.m.

|2. | BASIS OF PRESENTATION OF THE COMBINED FINANCIAL STATEMENTS.
|-- | -----------------------------------------------------------

2.1 Basis of preparation

The combined financial statements as of December 31, 2015 and 2014 of Enersis Chile have been prepared in accordance with International
Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB). They were approved by the Enersis Board Directors at its meeting held on April 29, 2016.

As of December 31, 2015, the Enersis Chile Combined Group does not represent a group for consolidated financial statement reporting
purposes in accordance with IFRS 10 Consolidated Financial Statements.

The accompanying combined financial statements reflect the
combined operations of the Combined Group as it would have been incorporated following the spin-off, assuming date would have been January 1, 2013. The combined financial statements may not be indicative of the Combined Groups future
performance and do not necessarily reflect what the results of operations, financial position and cash flows would have been had it operated, since January 1, 2013 as an independent Combined Group during the periods presented.

The Combined Group used the same accounting policies and valuation methods for the preparation of these combined financial statements, as those
used by Enersis for the preparation of its Consolidated Financial Statements, unless such accounting policies and valuation methods are not in accordance with IFRS when presenting the Combined Group as a group of companies independent of Enersis.
These accounting policies have been disclosed under this note and Note 3 Accounting policies. The entities and associates are included in these combined financial statements using their respective historical carrying values and amounts as included
in Enersis Consolidated Financial Statements.

Since IFRS does not provide any guidance for the preparation of combined financial
statements, paragraph 12 of IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors has been used for the preparation of the combined financial statements. This paragraph requires that the latest pronouncements of other standard
setters, other accounting literature and accepted industry practice should be considered. The combined financial statements of Enersis Chile have been derived from the aggregation of the net assets of the Chilean business of Enersis. All intra-group
balances, revenues, expenses and unrealized gains and losses arising from transactions between companies belonging to Combined Group were eliminated when preparing the combined financial statements. In addition, the investments of Enersis in the
Combined Group were eliminated against the equity of the respective combined entities. Transactions with Enersis group companies, which do not belong to the Combined Group, have been disclosed as transactions with related parties.

Principles applied in preparing the Combined Financial Statements

The following summarizes the accounting and other principles applied in preparing the combined financial statements. Enersis Management
considers that the allocations described below have been made on a reasonable basis, but are not necessarily indicative of the costs that would have been incurred if the Combined Group had been a stand-alone entity.

Net assets of the Parent (equity)

The Combined Group has not previously formed a separate legal group nor presented any stand-alone financial statements, and accordingly it is
not conceivable to present share capital or an analysis of equity reserves. The net assets of the Combined Group are represented by capital invested in the Combined Group and are shown as Equity using the same captions as those used by
Enersis. Issued capital, share premium and retained earnings of Enersis have been allocated to Enersis Chile based on net assets

value ratio assigned to it. Other reserves (which are primarily composed of the equity effects of past reorganizations, business combinations under common control, residual effects of first-time
adoption of IFRS and the equity effects of the current spin-off process) have been allocated considering the transaction and circumstances that led to creation of these reserves.

Cash and cash equivalents

Cash and cash equivalents of the foreign subsidiaries of Enersis are excluded from these Combined Financial Statements.

In addition, the cash and cash equivalents balance of Enersis, on a stand-alone basis, was allocated using the following criteria:



| | (i) | Cash and cash equivalents from the proceeds from the capital increase carried out in 2013 were excluded from these Combined Financial Statements; and
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | Cash and cash equivalents remaining after excluding the 2013 capital increase proceeds, were allocated based on the exercise carried out by Enersis management, the ratios obtained for the division of the cash and
cash equivalents, are as follows:
| | ---- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|               |  |                                     |     |  |          |  |     |

Intercompany balances and transactions with related companies

Intercompany balances with successors of Enersis were allocated by identifying the entity that provided/received the service as well as the
nature of it. Intercompany balances with Enersis Chile were eliminated in full for the purpose of these combined financial statements. Intercompany balances with Enersis Americas are included in these combined financial statements and disclosed as
accounts with related companies.

Debt instruments and related interest expenses, exchange differences and effects of hedge accounting
strategies

Financial debt and related interest expenses and exchange rate differences of the Chilean subsidiaries of Enersis are
included in these combined financial statements. Financial debt and related interest expenses and exchange rate differences of Enersis stand-alone have been 100% allocated to Enersis Americas and are not included in these combined financial
statements.

In relation to derivative instruments designated as hedging instruments for the Chilean subsidiaries of Enersis, these have
been included in these combined financial statements. Enersis management has adopted as a criterion to keep the strategies of hedge accounting. Therefore, all effects on the statement of financial position, income and other comprehensive
income are assigned to the specific companies to which the hedged items were assigned. In the case of Enersis on a stand-alone basis, the main items covered by the hedging strategies are related to debt (hedging exposure to foreign currency debt and
variability in interest rates). Therefore, the main derivative instruments associated with such hedging strategies have been assigned according to Enersis Américas, an entity that will assume 100% of the debt of Enersis stand-alone entity, or
Enersis Chile, as applicable.

Personnel, salary expenses other employee benefits

For purposes of properly distributing the accounting effect of personnel from Enersis on a stand-alone basis between Enersis Chile and Enersis
Américas, the Enersis Management defined as a criterion to identify those personnel whose main activities are related 100% with the operations based in Chile under Enersis. This group of employees was assigned to Enersis Chile. On the
other hand, Management also identified those employees whose main activities relate 100% to foreign operations. This group of employees was assigned to Enersis Américas.

All remaining personnel, who divide their main activities between the Chilean operations of Enersis and foreign operations, were assigned to
Enersis Chile, meaning that from the date of the spin-off, those employees would identify the activities offered to foreign operations of Enersis and vice-versa. The existing contracts of the inter-company provision of services between foreign and
local businesses ensure reimbursement of the incurred costs of these employees that have been allocated based on the time dedicated to activities offered to Enersis Chile companies from their total available time.

Enersis Américas:

Once the allocation of personnel was determined Enersis management applied the following criterion to the
division of all the personnel related accounts in the statements of financial position and comprehensive income that were associated with the costs directly related to the personnel, such as wages and salaries, post-employment benefit obligations
expense and social security and other benefits, travel expenses, etc. In this regard their allocation was performed based on the specific assignment of the related personnel to the Combined Group, as described above.

Other shared costs

The
combined statements of income include expense allocations for certain corporate functions provided by Enersis, including, but not limited to, human resources administration, treasury, risk management, internal audit, accounting, tax, legal,
insurance, medical services, information technology support, communication management, and other shared services. These expenses were allocated to Enersis Chile and Enersis Américas based on a specific identification basis, and in other cases
these expenses were allocated by Enersis based on a pro-rata basis of headcount or some other basis depending on the nature of the allocated cost. Management considers the basis on which the expenses have been allocated to reasonably reflect the
utilization of services provided to or the benefit received by Enersis Chile during the periods presented.

Dividends receivable and
payable

The criterion defined by Enersis Management to allocate to both Enersis Chile as well as to Enersis Américas a
portion of dividends receivable accounts from Enersis stand-alone as of the date of the corporate spin-off, has been based mainly on identifying the origin of each one of those dividends. If the dividends come directly from a Chilean subsidiary,
these dividends have been allocated 100% to Enersis Chile.

Income tax

The tax effect (income statement and income tax provision) related to the Chilean subsidiaries of Enersis are included in these combined
financial statements and was calculated using the statutory corporate tax rates according to the jurisdiction where the pre-tax income was originated.

In addition, for the tax effect in the income statement of Enersis on a stand-alone basis it has been allocated to these combined financial
statements by determining a hypothetical taxable income as if Enersis Chile and Enersis Americas had operated as separate taxpayers. However, and from a tax point of view, there is currently only one taxpaying company, which is Enersis, and whose
successor entity would be Enersis Americas. Accordingly, income tax payable by Enersis has not been allocated to the combined financial statements.

In relation to deferred tax assets and liabilities, these have been assigned to Enersis Chile and Enersis Américas, taking into account
the underlying assets and liabilities, whose respective temporary differences have originated such deferred taxes.

Other working
capital accounts

Working capital items such as accounts receivable, accounts payable and inventories that are directly attributable to
the Chilean operations of the Combined Group are included in the combined financial statements.

##### Table of Contents

Standards, Interpretations and Amendments

Mandatory application for:Amendment to IAS 1: Disclosure Initiative 
The IASB has issued amendments to IAS 1 as part of its principal initiative to improve the presentation and disclosure of information in financial
statements. These amendments are designed to assist companies in applying professional judgment to determine the disclosures that should be included in their financial statements.

Annual periods beginning on orafter January 1, 2016.Amendment to IFRS 10, IFRS 12 and IAS 28: Investment Entities, Application of the Consolidation Exception
 The amendments, which have a restricted scope, introduce clarifications to the
requirements for the accounting of investment entities. The modifications also provide relief in some circumstances, which will reduce the costs of applying the Standards.

Annual periods beginning on orafter January 1, 2016.IFRS 9: Financial Instruments 
This is the final version of the standard issued in July 2014 and which completes the IASB project to replace IAS 39 Financial Instruments:
Recognition and Measurement. This project was divided into 3 phases: 
Phase 1  Classification and measurement of financial assets and financial liabilities. This introduces a logical focus for the classification of
financial assets driven by cash flow characteristics and the business model. This new model also results in a single impairment model being applied to all financial instruments.
 Phase 2  Impairment methodology. The objective is a more timely recognition of
expected credit losses. The standard requires entities to account for expected credit losses from the time when financial instruments are first recognized in the financial statements.
 Phase 3  Hedge accounting. This establishes a new model aimed at reflecting
better alignment between hedge accounting and risk management activity. Also included are enhancements to required disclosures. 
This final version of IFRS 9 replaces the previous versions of the Standard.

Annual periods
beginning on orafter January 1, 2018.IFRS 15: Revenue from Contracts with Customers 
This new standard applies to all contracts with customers except leases, financial instruments and insurance contracts. Its purpose is to make financial
information more comparable, and it provides a new model for revenue recognition and more detailed requirements for contracts with multiple obligations. It also requires more itemized information. This standard will replace IAS 11 and IAS 18 as well
as their interpretations (IFRIC 13, IFRIC 15, IFRIC 18 and SIC 31).

Annual periods beginning on orafter January 1, 2018.IFRS 16: Leases 
This new standard provides a definition of a lease contract and specifies the accounting treatment for the assets and liabilities originated under those
contracts from both lessor and lessee perspective. Lessor accounting remains largely unchanged from its predecessor IAS 17, Leases. However, for lessee accounting, the new standard requires recognition of a right of use an asset and a corresponding
liability, similar to finance lease accounting under IAS 17 for most lease contracts.

Annual periods beginning on orafter January 1, 2019.


The Combined Group is currently assessing the impact of applying IFRS 9, IFRS 15, and IFRS 16; however,
it is not practicable to provide a reasonable estimate of the effects that these IFRSs will have until the Combined Group performs a detail review. In Enersis managements opinion, the future application of the other standards and amendments is
not expected to have a significant effect on the combined financial statements of the Combined Group.

2.3 Responsibility for the information, judgments and estimates
provided

Management is responsible for the information contained in these combined financial statements and expressly states that all
IFRS principles and standards, as issued by the IASB, have been fully implemented.

In preparing the combined financial statements, certain
judgments and estimates made by management have been used to quantify some of the assets, liabilities, income, expenses and commitments recorded in the statements.

The most important areas were critical judgment is required are:



| |  |  | The identification of Cash Generating Units (CGU) for impairment testing (see Note 3.e).
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | The hierarchy of information used to measure assets and liabilities at fair value (see Note 3.h)
| | - |  | ------------------------------------------------------------------------------------------------

The estimates refer basically to:



| |  |  | The valuations performed to determine the existence of impairment losses among tangible and intangible assets and goodwill (see Note 3.e).
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The assumptions used to calculate the actuarial liabilities and obligations to employees, such as discount rates, mortality tables, salary raises, etc. (see Notes 3.m.1 and 25).
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The useful life of property, plant and equipment, and intangible assets (see Notes 3.a and 3.d).
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | The assumptions used to calculate the fair value of financial instruments (see Notes 3.g.5 and 22).
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | Energy supplied to customers whose meter readings are pending.
| | - |  | --------------------------------------------------------------



| |  |  | Certain assumptions inherent in the electricity system affecting transactions with other companies, such as production, customer billings, energy consumption, etc. that allow for estimating electricity system
settlements that must occur on the corresponding final settlement dates, but that are pending as of the date of issuance of the combined financial statements and could affect the balances of assets, liabilities, income and expenses recorded in the
statements (see appendix 6.2).
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The probability that uncertain or contingent liabilities will be incurred and their related amounts (see Note 3.l).
| | - |  | -------------------------------------------------------------------------------------------------------------------



| |  |  | Future disbursements for the closure of facilities and restoration of land, as well as the discount rates to be used (see Note 3.a).
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The tax results of the various combined entities of the Combined Group that will be reported to the respective tax authorities in the future, and that have served as the basis for recording different balances related to
income taxes in these combined financial statements (see Note 3.o).
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The fair values of assets acquired and liabilities assumed, and any pre-existing interest in an entity acquired in a business combination.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------

Although these judgments and estimates have been based on the best information available on the issuance date of these combined financial
statements, future events may occur that would require a change (increase or decrease) to these estimates in subsequent periods. This change would be made prospectively, recognizing the effects in the corresponding future combined financial
statements.

2.4 Combined entities

The Combined Group consists of the entities indicated in Appendix 1, which shown the entities that will be part of the Enersis Chiles
Group, as well as, a description of the relationship that Enersis Chile will have with each of its combined entities, which have been considered in terms of the preparation of these combined financial statements.

Combined entities are those entities that will be controlled, either directly or indirectly, by the Combined Group. Control is achieved when a
company has i) power over the combined entity; ii) is exposed, or has rights, to variable returns from its involvement with the combined entity; and iii) has the ability to use its power to affect its returns.

A company has power over entity when it holds the majority of the substantive voting rights or, when it has less than a majority of the voting
rights, and those rights are sufficient to give it the practical ability to direct the relevant activities of the entity unilaterally. Control over an entity is reassessed if facts and circumstances indicate that there are changes to one or more of
the three elements of control listed above.

2.4.1 Changes in the scope of combination

On January 9, 2015, our combined entity Empresa Nacional de Electricidad S.A. (Endesa Chile S.A.), sold all the shares owned in Sociedad
Concesionaria Túnel El Melón S.A. for ThCh$25,000,000 (see Note 5).

The elimination of Sociedad Concesionaria Túnel
El Melón S.A. from Enersis Combined Groups scope of combination caused a decrease in the combined statement of financial position of ThCh$871,022 in current assets, ThCh$7,107,941 in non-current assets, ThCh$3,698,444 in current
liabilities and ThCh$1,789,703 in non-current liabilities.

On December 30, 2014, Inmobiliaria Manso de Velasco Ltda, a combined
entity of Enersis, completed the sale of all of its direct and indirect ownership interest in the companies Construcciones y Proyectos Los Maitenes S.A. and Aguas Santiago Poniente S.A. The selling price of these shares was ThCh$57,173,143, which
was received in cash on the same date (see note 32).

The elimination of Maitenes S.A. and Aguas Santiago Poniente S.A. from the Enersis
Combined Groups scope of combination caused a decrease in the combined statement of financial position of ThCh$54,845,853 in current assets, ThCh$12,822,077 in non-current assets, and ThCh$1,393,348 in current liabilities; there was no effect
on non-current liabilities.

During the first half of 2014, the company Inversiones GasAtacama Holding Limitada was incorporated to the
Enersis Combined Groups scope of combination as a result of Endesa Chile S.A.s acquisition of a 50% interest in that company on April 22, 2014 (see Note 6).

Pursuant to this operation, the following companies became combined entities of the Combined Group: Inversiones GasAtacama Holding Limitada,
GasAtacama S.A., GasAtacama Chile S.A., Gasoducto TalTal S.A., Progas S.A., Gasoducto Atacama Argentina S.A., Atacama Finance Co., GNL Norte S.A. and Energex Co.

The incorporation of GasAtacama Holding Limitada to the Enersis Combined Groups scope of combination resulted in an increase in the
combined statement of financial position of ThCh$198,924,289 in current assets, ThCh$221,471,415 in non-current assets, ThCh$69,989,919 in current liabilities, and ThCh$35,672,488 in non-current liabilities.

2.4.2 Uncombined companies with an ownership interest of more than 50%

Although the Combined Group holds more than a 50% ownership interest in Centrales Hidroeléctricas de Aysén S.A. (Aysén),
it is considered a joint venture since the Combined Group, through contracts or agreements with shareholders, exercises joint control of the company.

2.5 Investment in associates and joint arrangements

Associates are those in which the Combined Group, either directly or indirectly, exercises significant influence.

Significant influence is the power to participate in the financial and operational policy decisions of the associate but does not control or
have joint control over those policies. In general, significant influence is presumed to be those cases in which the Combined Group has an ownership interest of more than 20% (see Note 3.i).

Joint arrangements are defined as those entities in which the Combined Group exercises control under an agreement with other shareholders and
jointly with them, in other words, when decisions on the entities relevant activities require the unanimous consent of the parties sharing control. Joint arrangements are classified as:



| |  |  | Joint ventures: an agreement whereby the parties exercising joint control have rights to the entitys net assets.
| | - |  | -----------------------------------------------------------------------------------------------------------------



| |  |  | Joint operation: an agreement whereby the parties exercising joint control have rights to the assets and obligations with respect to the liabilities relating to the arrangement. Currently, Enersis Chile does not have
any joint arrangements that qualify as joint operations.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Appendix 3  Associated Companies and Joint
Ventures to these combined financial statements describes the relationship of Enersis Chile with each of these companies.

2.6 Business combinations

The combined entities are combined and all their assets, liabilities, revenues, expenses, and cash flows
are included in the combined financial statements once the adjustments and eliminations from intercompany transactions have been made.

The
comprehensive income of combined entities is included in the combined statement of comprehensive income from the date when the Combined Group obtains control of the combined entity and until the date on which it loses control of the combined entity.

##### Table of Contents

The operations of the Combined Group and its combined entities have been combined under the
following principles:



| | 1. | At the date Enersis Chile obtains control, the combined entitys assets acquired and its liabilities assumed are recorded at fair value, except for certain assets and liabilities that are recorded using valuation
principles established in other IFRS standards. If the fair value of the consideration transferred plus the fair value of any non-controlling interest exceeds the fair value of the net assets acquired, this difference is recorded as goodwill. In the
case of a bargain purchase, the resulting gain is recognized in profit or loss for the period after reassessing whether all of the assets acquired and the liabilities assumed have been properly identified and following a review of the procedures
used to measure the fair value of these amounts.
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

For each business combination, the Combined Group chooses whether to
measure the non-controlling interests in an acquired company at fair value or at the proportional share of the net identifiable assets acquired.

If the fair value of assets acquired and liabilities assumed at the acquisition date it has not been completed, the Combined Group reports the
provisional values recorded. During the measurement period, which shall not exceed one year from the acquisition date, the provisional values recognized will be adjusted retrospectively and additional assets or liabilities will be recognized to
reflect new information obtained on events and circumstances that existed on the acquisition date, but which were unknown to management at that time.

For business combinations achieved in stages, the fair value of the equity interest previously held in the acquired company is measured on the
date of acquisition and any profit or loss is recognized in the results for that fiscal year.



| | 2. | Non-controlling interests in equity and in the comprehensive income of the combined entities are presented, respectively, under the line items Total Equity: Non-controlling interests in the combined
statement of financial position and Net Income attributable to non-controlling interests and Comprehensive income attributable to non-controlling interests in the combined statement of comprehensive income.

| | 3. | The financial statements of combined entities with functional currencies other than the Chilean peso are translated as follows:
| | -- | -------------------------------------------------------------------------------------------------------------------------------



| | a. | For assets and liabilities, the prevailing exchange rate on the closing date of the financial statements is used.
| | -- | -----------------------------------------------------------------------------------------------------------------



| | b. | For items in the comprehensive income statement, the average exchange rate for the period is used (unless this average is not a reasonable approximation of the cumulative effect of the exchange rates in effect on the
dates of the transactions, in which case the exchange rate in effect on the date of each transaction is used).
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | c. | Equity remains at the historical exchange rate from the date of acquisition or contribution, and retained earnings at the average exchange rate at the date of origination.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | d. | Exchange differences arising in translation of financial statements are recognized in the item Foreign currency translation gains (losses) in other comprehensive income (see Note 26.2).
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In 2015, the assessment of the functional currency of Inversiones GasAtacama Holding Ltda. was revised and we determined the Chilean Peso as
its functional currency. Our decision to change the functional currency was made considering that upon integration of operations of this entity it became an extension of its immediate parent Endesa Chile, as such, have the same functional currency,
that is, the Chilean peso. The change was applied prospectively.



| | 4. | Balances and transactions between combined entities were fully eliminated in the combination process.
| | -- | -----------------------------------------------------------------------------------------------------



| | 5. | Changes in interests in combined entities that do not result in taking or losing control are recorded as equity transactions, and the book value of the controlling and non-controlling interests is adjusted to reflect
the change in relative interest in the combined entity. Any difference that may exist, between the value for which a non-controlling interest is adjusted and the fair value of a compensation paid or received, is recognized directly in Equity
attributable to Enersis Chile.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 6. | Business combinations under common control are recorded using, as a reference, the pooling of interest method. Under this method, the assets and liabilities involved in the transaction remain reflected at
the same book value at which they were recorded in the ultimate controlling company, although subsequent accounting adjustments may need to be made to align the accounting policies of the companies involved.
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Any difference between the assets and liabilities contributed to the combination and the compensation given is recorded directly in Net equity
as a debit or credit to other reserves. The Combined Group does not apply retrospective accounting records of business combinations under common control.

|3. | ACCOUNTING POLICIES APPLIED.
|-- | ----------------------------

The main accounting policies used in preparing the
accompanying combined financial statements are the following:

a) Property, plant and equipment

Property, plant and equipment are measured at acquisition cost, net of accumulated depreciation and any impairment losses they may have
experienced. In addition to the price paid to acquire each item, the cost also includes, where applicable, the following concepts:



| |  |  | Financing expenses accrued during the construction period that are directly attributable to the acquisition, construction, or production of qualified assets, which require a substantial period of time before being ready
for use such as, for example, electricity generation or distribution facilities. The Combined Group defines substantial period as one that exceeds twelve months. The interest rate used is that of the specific financing or, if none
exists, the weighted average financing rate of the company carrying out the investment. (See Note 17.b.1).
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Employee expenses directly related to construction in progress. (See Note 17.b.2).
| | - |  | ----------------------------------------------------------------------------------



| |  |  | Future disbursements that the Combined Group will have to incur to close its facilities are added to the cost of the asset, recognizing the corresponding provision for dismantling or restoration. The Combined Group
reviews its estimates on an annual basis, increasing or decreasing the value of the asset and the liability based on the results of this estimate (see Note 24).
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Items for construction work in progress are transferred to operating assets once the testing period has been completed and they are available
for use, at which time depreciation begins.

Expansion, modernization or improvement costs that represent an increase in productivity,
capacity or efficiency, or a longer useful life are capitalized as increasing the cost of the corresponding assets.

The replacement or
overhaul of entire components that increase the assets useful life or economic capacity are recorded as an increase in cost for the respective assets, derecognizing the replaced or overhauled components.

Expenditures for periodic maintenance, conservation and repair are recognized directly as an expense for the year in which they are incurred.

The Combined Group, based on the outcome of impairment testing performed as explained in Note 3.e), considers that the carrying amount of
assets does not exceed their recoverable amount.

Property, plant and equipment, net of its residual value, is depreciated by distributing
the cost of the different items that comprise it on a straight-line basis over its estimated useful life, which is the period during which the Combined Group expects to use the assets. Useful life estimates and residual values are reviewed on an
annual basis and if appropriate adjusted prospectively.

The following table sets forth the main categories of property, plant and
equipment with their respective estimated useful lives:



|                                            |  |

|Fixtures and fittings                       |  | 5 - 21                        
|Motor vehicles                              |  | 5 - 10                        
|Other                                       |  | 2 - 33

Land is not depreciated since it has an indefinite useful life.

Gains or losses that arise from the sale or disposal of items of Property, plant and equipment are recognized as Other gains
(losses) in the comprehensive income statement and are calculated by deducting the net carrying amount of the asset and any sales expenses from the amount received in the sale.

b) Investment property

Investment property includes land and buildings held for the purpose of earning rentals and/or for capital appreciation.

Investment property is measured at acquisition cost less any accumulated depreciation and impairment losses that have been incurred. Investment
property, excluding land, is depreciated on a straight-line basis over the useful lives of the related assets.

An investment property is
derecognized upon disposal or when no future economic benefits are expected from its use or disposal.

Gains or losses on derecognition of
the investment property is calculated as the difference between the net disposal proceeds and the carrying amount of the asset.

The
breakdown of the fair value of investment property is detailed in Note 18.

c) Goodwill

Goodwill arising from business combinations represents the excess of the consideration paid plus the amount of any non-controlling interests
over the Combined Groups share of the net value of the assets acquired and liabilities assumed, measured at fair value at the acquisition date. If the accounting for a business combination is completed, as well as the determination of
goodwill, after the end of the reporting period in which the combination occurs, the amounts previously reported presented are adjusted, for comparative purposes to include the value of the assets acquired and liabilities assumed and the value of
the final goodwill as of acquisition date.

Goodwill arising from acquisition of entities with functional currencies other than the Chilean
peso is measured in the functional currency of the acquired company and translated to Chilean pesos using the closing exchange rate.

Goodwill is not amortized; instead, at the end of each reporting period or when there are indicators that an impairment might have occurred,
the Combined Group estimates whether any impairment loss has reduced its recoverable amount to an amount less than the carrying amount and, if so, it impairment loss is immediately recognized in profit or loss (see Note 3.e).

d) Intangible assets other than goodwill

Intangible assets are initially recognized at their acquisition cost or production cost, and are subsequently measured at their cost, net of
their accumulated amortization and impairment losses they may have experienced.

Intangible assets are amortized on a straight line basis
during their useful lives, starting from the date when they are ready for use, except for those with an indefinite useful life, which are not amortized. As of December 31, 2015 and 2014, there are no significant intangible assets with an
indefinite useful life.



F-24

##### Table of Contents

An intangible asset is derecognized on disposal, or when no future economic benefits are expected
from use or disposal.

Gains or losses arising from derecognition of an intangible asset, measured as the difference between the net
disposal proceeds and the carrying amount of the asset are recognized in profit or loss when the asset is derecognized.

The criteria for
recognizing these assets impairment losses and, if applicable, recovery of impairment losses recorded in previous fiscal years are explained in Note 3.e below.

d.1) Research and development expenses

The Combined Group recognizes the costs incurred in a projects development phase as intangible assets in the statement of financial
position as long as the projects technical feasibility and future economic benefits have been demonstrated.

d.2) Other intangible assets

Other intangible assets correspond to computer software, water rights, and easements. They are
initially recognized at acquisition or production cost and are subsequently measured at cost less accumulated amortization and impairment losses, if any.

Computer software is amortized (on average) over five years. Certain easements and water rights have indefinite useful lives and, therefore,
are not amortized, while others have useful lives ranging from 40 to 60 years, depending on their characteristics, and they are amortized over that term.

e) Impairment of non-financial assets

During the year, and principally at the end of each reporting period, the Combined Group evaluates whether there is any indication that an
asset has been impaired. If any such indication exist, the Combined Group estimates the recoverable amount of that asset to determine the amount of the impairment loss. In the case of identifiable assets that do not generate cash flows
independently, the Combined Group estimates the recoverable amount of the Cash Generating Unit (CGU) to which the asset belongs, which is understood to be the smallest identifiable group of assets that generates independent cash inflows.

Notwithstanding the preceding paragraph, in the case of CGUs to which goodwill or intangible assets with indefinite useful lives have been
allocated, a recoverability analysis is performed routinely at each period end.

Recoverable amount is the higher of fair value less costs
of disposal and value in use, which is defined as the present value of the estimated future cash flows. In order to calculate the recoverable amount of Property, plant, and equipment, as well as of goodwill, and intangible assets, the Combined Group
uses value in use criteria in practically all cases.

To estimate value in use, the Combined Group prepares future pre-tax cash flow
projections based on the most recent budgets available. These budgets incorporate managements best estimates of a CGUs revenue and costs using sector projections, past experience and future expectations.

In general, these projections cover the next five years, estimating cash flows for subsequent years by applying reasonable growth rates which,
in no case, are increasing rates nor exceed the average long-term growth rates for the particular sector and country in which the Combined Group operates. For the years ended December 31, 2015, 2014 and 2013, projections were extrapolated from
the following rates:



|                 |  |             |  |            
|---------------- |  | ----------- |  | -----------
|Growth rates (g)
|2015             |  | 2014        |  | 2013       
|4.5%  5.1%      |  | 2.2%  5.0% |  | 2.2%  5.3%

Future cash flows are discounted to calculate their present value at a pre-tax rate that covers the cost of
capital for the business activity and the geographic area in which it is being carried out. The time value of money and risk premiums generally used among analysts for the business activity and the geographic zone are taken into account to calculate
the pre-tax rate.

The following are the pre-tax discount rates applied in 2015, 2014 and 2013 expressed in nominal terms:



|        |  |         |  |         |  |         |  |         |  |        
|------- |  | ------- |  | ------- |  | ------- |  | ------- |  | -------
|2015    |  | 2014    |  | 2013   
|Minimum |  | Maximum |  | Minimum |  | Maximum |  | Minimum |  | Maximum
|8.1%    |  | 12.7%   |  | 7.9%    |  | 13.0%   |  | 7.8%    |  | 16.3%  



F-25



---

##### Table of Contents

If the recoverable amount of the CGU is estimated to be less than the net carrying amount of the
asset, the corresponding impairment loss is recognized for the difference, and charged to Reversal of impairment loss (impairment loss) recognized in profit or loss in the combined statement of comprehensive income. The impairment
is first allocated to reduce the carrying amount of any goodwill allocated to the CGU, and then to the other assets of the unit pro rata on the basis of the carrying amount of each asset in the unit. The carrying amount of an asset is not reduced
below the highest of fair value less costs of disposal, its value in use; or zero.

Impairment losses recognized for an asset in prior
periods are reversed when there are indications that the impairment loss no longer exists or may have decreased, thus increasing the assets carrying amount with a credit to earnings. The increase in the assets carrying amount shall not
exceed that carrying amount that would have been determined had no impairment loss been recognized for the asset. Goodwill impairment losses are not reversed in subsequent periods.

f) Leases

In order to determine whether an arrangement is, or contains, a lease, the Combined Group assesses the economic substance of the agreement, in
order to determine whether fulfillment of the arrangement depends on the use of a specific asset and whether the agreement conveys the right to use an asset. If both conditions are met, at the inception of the arrangement the Combined Group
separates the payments and other considerations relating to the lease, at their fair values, from those corresponding to other components of the agreement.

Leases that substantially transfer all the risks and rewards of ownership to the Combined Group are classified as finance leases. All others
leases are classified as operating leases.

Finance leases in which the Combined Group acts as a lessee are recognized at the inception of
the arrangement. At that time, the Combined Group records an asset based on the nature of the lease and a liability for the same amount, equal to the fair value of the leased asset or the present value of the minimum lease payments, if the latter is
lower. Subsequently, the minimum lease payments are apportioned between finance expenses and reduction of the lease obligation. Finance expenses are recognized immediately in the income statement and allocated over the lease term, so as to achieve a
constant interest rate on the remaining balance of the liability. Leased assets are depreciated on the same terms as other similar depreciable assets, as long as there is reasonable certainty that the lessee will acquire ownership of the asset at
the end of the lease. If no such certainty exists, the leased assets are depreciated over the shorter of the useful lives of the assets and their lease term.

In the case of operating leases, payments are recognized as an expense in the case of the lessee and as income in the case of the lessor, both
on a straight-line basis, over the term of the lease unless another type of systematic basis of distribution is deemed more representative.

g) Financial instruments

Financial instruments are contracts that give rise to both a financial asset in one entity and a financial liability or equity instrument in
another entity.

g.1) Financial assets other than derivatives

The Combined Group classifies its financial assets other than derivatives, whether permanent or temporary, except for investments accounted for
using equity method (See Note 14) and those held for sale, into four categories:



| |  |  | Loans and account receivables: Trade and other receivables and accounts receivable from related companies are recognized at amortized cost, which is the initial fair value less principal repayments made, plus
accrued and uncollected interest, calculated using the effective interest method.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The effective interest method is used to
calculate the amortized cost of a financial asset or liability (or group of financial assets or financial liabilities) and of allocating finance income or cost over the relevant period. The effective interest rate is the rate that exactly discounts
estimated future cash flows to be received or paid over the expected life of the financial instrument or, when appropriate, a shorter period to the net carrying amount of the financial asset or financial liability.



| |  |  | Held-to-maturity investments: Investments that the Combined Group intends to hold and is capable of holding until their maturity are accounted for at amortized cost as defined in the preceding paragraph.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Financial assets at fair value with changes in net income: This category includes the trading portfolio and those financial assets that have been designated as such upon initial recognition and that are managed
and evaluated on a fair value basis. They are measured in the combined statement of financial position at fair value, with changes in value recorded directly in income when they occur.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



F-26



---

##### Table of Contents

| |  |  | Available-for-sale financial assets: These are financial assets specifically designated as available-for-sale or are not classify within any of the three preceding categories.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

These investments are recognized in the combined statement of financial position at fair value when it can be reliably determined. For
investments in equity instruments in unlisted companies or companies with lower levels of liquidity, normally the fair value cannot be reliably measured. When this occurs, those investments in equity instruments are measured at cost less impairment
losses, if any.

Changes in fair value, net of taxes, are recognized in other comprehensive income, until the investments are disposed of,
at which time the amount accumulated in other comprehensive income is reclassified to profit or loss.

If the fair value is lower than
cost, and if there is objective evidence that the asset has been more than temporarily impaired, the difference is recognized directly in profit or loss.

Purchases and sales of financial assets are accounted for using their trade date.

g.2) Cash and cash equivalents

This item within the combined statement of financial position includes cash and bank balances, time deposits, and other highly liquid
investments (with original maturity of less than or equal to 90 days) that are readily convertible to cash and are subject to insignificant risk of changes in value.

g.3) Impairment of financial assets

The following criteria are used to determine if a financial asset has been impaired:



| |  |  | For trade receivables in the electricity generation, transmission and distribution segments, the Combined Groups policy is to recognize impairment losses when there is objective evidence that the balance will not
be recoverable. In general terms, the Combined Groups entities has a defined policy to recognize an allowance for impairment losses based on the aging of past-due balances, except in those cases where a specific collective basis analysis is
recommended, such as in the case of receivables from government-owned companies (see Note 10).
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In the case of receivables of a financial nature, that are included in the Loan and receivables and Investment held-to-maturity, impairment is determined on case-by-case basis and is measured as
the difference between the carrying amount and the present value of the future estimated cash flows discounted at the original effective interest rate (see Notes 9 and 22).
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | For financial investments available-for-sale, the criteria for impairment applied are described in Note 3.g.1
| | - |  | -------------------------------------------------------------------------------------------------------------

g.4) Financial liabilities other than derivatives

Financial liabilities are recognized based on cash received, net of any costs incurred in the transaction. In subsequent periods, these
obligations are measured at their amortized cost using the effective interest rate method (see Note 3.g.1).

In the particular case that a
liability is the hedged item in a fair value hedge, as an exception, such liability is measured at its fair value for the portion of the hedged risk.

In order to calculate the fair value of debt, both when it is recorded in the statement of financial position and for fair value disclosure
purposes as shown in Note 22, debt has been divided into fixed interest rate debt (hereinafter fixed-rate debt) and variable interest rate debt (hereinafter floating-rate debt). Fixed-rate debt is that on which fixed-interest
coupons established at the beginning of the transaction are paid explicitly or implicitly over its term. Floating-rate debt is that debt issued at a variable interest rate, i.e., each coupon is established at the beginning of each period based on
the reference interest rate. All debt has been measured by discounting expected future cash flows with a market interest rate curve based on the payment currency.

g.5) Derivative financial instruments and hedge accounting

Derivatives held by the Combined Group are transactions entered into to hedge interest and/or exchange rate risk, intended to eliminate or
significantly reduce these risks in the underlying transactions being hedged.

Derivatives are recorded at fair value at the end of each
reporting period as follows: if their fair value is positive, they are recorded within Other financial assets; and if their fair value is negative, they are recorded within Other financial liabilities. For derivatives on
commodities, the positive fair value is recorded in Trade and other receivables, and negative fair values are recorded in Trade and other liabilities.



F-27



---

##### Table of Contents

Changes in fair value are recorded directly in profit or loss, except when the derivative has
been designated for hedge accounting purposes as a hedge instrument (in a cash flow hedge) and all of the conditions for applying hedge accounting are met, including that the hedge be highly effective. In this case, changes are recorded as follows:



| |  |  | Fair value hedges: The underlying portion for which the risk is being hedged (hedged risk) and the hedge instrument are measured at fair value, and any changes in value of both items are recognized in the
combined statement of comprehensive income by offsetting the effects in the same comprehensive income statement account.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Cash flow hedges: Changes in fair value of the effective portion of the hedged item and hedge instrument are recorded in other comprehensive income an accumulated in an equity reserve known as Reserve for
cash flow hedges. The cumulative gain or loss in in this reserve is reclassified to the combined statement of comprehensive income to the extent that the hedged item impacts the combined statement of comprehensive income offsetting the effect
in the same comprehensive income statement account. Gains or losses from the ineffective portion of the hedging relationship are recorded directly in the combined statement of comprehensive income.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

A hedge relationship is considered highly effective when changes in fair value or in cash flows of the underlying item directly attributable to
the hedged risk are offset by changes in fair value or cash flows of the hedging instrument, with an effectiveness ranging from 80% to 125%.

As a general rule, long-term commodity purchases or sales agreements are recorded in the combined statement of financial position at their fair
value at the end of each reporting period, recognizing any differences in value directly in profit or loss, except for, when all of the following conditions are met:



| |  |  | The sole purpose of the agreement is for the Combined Groups own use, which is understood as: (i) in the case of fuel purchase agreements its used to generate electricity; (ii) in the case of electrical
energy purchased for sale, its sale to the end-customers; and, (i) in the case of electricity sales its sale to the end-customers.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The Combined Groups future projections evidence the existence of these agreements for its own use.
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | Past experience with agreements evidence that they have been utilized for the Combined Groups own use, except in certain isolated cases when for exceptional reasons or reasons associated with logistical issues
have been used beyond the control and projection of the Combined Group.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The agreement does not stipulate settlement by differences and the parties have not made it a practice to settle similar contracts with differences in the past.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------

The long-term commodity purchase or sale agreements maintained by the Combined Group, which are mainly for electricity, fuel, and other
supplies, meet the conditions described above. Thus, the purpose of fuel purchase agreements is to use them to generate electricity, electricity purchase contracts are used to sell to end-customers, and electricity sale contracts are used to sell
the Combined Groups own products.

The Combined Group also evaluates the existence of derivatives embedded in contracts or financial
instruments to determine if their characteristics and risk are closely related to the principal contract, provided that when taken as a whole they are not being accounted for at fair value. If they are not closely related, they are recorded
separately and changes in value are accounted for directly in the comprehensive income statement.

g.6)
Derecognition of financial assets and liabilities

Financial assets are derecognized when:



| |  |  | The contractual rights to receive cash flows from the financial asset expire or have been transferred or, if the contractual rights are retained, the Combined Group has assumed a contractual obligation to pay these cash
flows to one or more recipients.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The Combined Group has substantially transferred all the risks and rewards of ownership of the financial asset, or, if it has neither transferred nor retained substantially all the risks and rewards, when it does not
retain control of the financial asset.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Transactions in which the Combined Group retains substantially all the inherent risks
and rewards of ownership of the transferred asset, it continues recognizing the transferred asset in its entirety and recognizes a financial liability for the consideration received. Transactions costs are recognized in profit and loss by using the
effective interest method (see Note 3.g.1).

Financial liabilities are derecognized when they are extinguished, that is, when the
obligation arising from the liability has been paid or cancelled, or has expired.

g.7) Offsetting financial assets and liabilities.

The Combined Group offsets financial assets and liabilities and the net amount is presented in the statement of financial position when, and
only when:



| |  |  | There is a legally enforceable right to set off the recognized amounts; and
| | - |  | ---------------------------------------------------------------------------



| |  |  | There is an intention to settle on a net basis, or to realize the asset and settle the liability simultaneously.
| | - |  | ----------------------------------------------------------------------------------------------------------------

g.8) Financial guarantee contracts

Financial guarantee contracts, such as guarantees given by the Combined Group to third parties, are initially recognized at fair value,
adjusting the transaction costs that are directly attributable to the issuance of the guarantee.

Subsequently to initial recognition,
financial guarantee contracts are measured at the higher of:



| |  |  | the amount determined under accounting policy describe in Note 3.l; and
| | - |  | -----------------------------------------------------------------------



| |  |  | the amount initially recognized less, if appropriate, any accumulated amortization.
| | - |  | -----------------------------------------------------------------------------------

h) Measurement of fair value

The fair value of an asset or liability is defined as the price that would be received from the sale
of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.

Fair value
measurement assumes that the transaction to sell an asset or transfer a liability occurs in the principal market, namely, the market with the greatest volume and level of activity for that asset or liability. In the absence of a principal market, it
is assumed that the transaction is carried out in the most advantageous market available to the entity, namely, the market that maximizes the amount that would be received to sell the asset or minimizes the amount that would be paid to transfer the
liability.

In estimating fair value, the Combined Group uses valuation techniques that are appropriate for the circumstances and for which
there are sufficient data to conduct the measurement. The Combined Group maximizes the use of relevant observable data and minimizes the use of unobservable data.

Considering the hierarchy of the data used in these valuation techniques, the assets and liabilities measured at fair value can be classified
into the following levels:



Level 1:

Quoted prices (unadjusted) in active markets for identical assets or liabilities;Level 2:

Inputs other than quoted prices included within Level 1 that are observable for the assets or liabilities, either directly (i.e. as prices) or indirectly (i.e. derived from prices). The methods and assumptions used to determine the
fair values at Level 2 by type of financial asset or financial liability take into consideration estimated future cash flows discounted at zero coupon interest rate curves for each currency. All the valuations described are carried out using
external tools, such as Bloomberg.Level 3:

Inputs for assets or liabilities that are not based on observable market data (unobservable inputs).


The Combined Group takes into account the characteristics of the asset or liability when measuring fair
value, in particular:



| |  |  | For non-financial assets, fair value measurement takes into account the ability of a market participant to generate economic benefits by using the asset in its highest and best use or by selling it to another market
participant that would use the asset in its highest and best use;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | For liabilities and equity instruments, the fair value measurement assumes that the liability would not be settled and an equity instrument would not be cancelled or otherwise extinguished on the measurement date. The
fair value of the liability reflects the effect of non-performance risk, namely, the risk that an entity will not fulfill the obligation, which includes, but is not limited to, the Combined Groups own credit risk;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | For derivatives non-quoted in an organized market, the Combined Group measures derivatives not traded on active markets by using the discounted cash flow method and generally accepted options valuation models, based on
current and future market conditions as of year-end. It also adjusts the value according to its own credit risk (Debt Valuation Adjustment, DVA), and the counterparty risk (Credit Valuation Adjustment, CVA). These CVA and DVA adjustments are
measured on the basis of the potential future exposure of the instrument (creditor or borrower position) and the risk profile of both the counterparties and the Combined Group itself.

##### Table of Contents

| |  |  | In the case of financial assets and financial liabilities with offsetting positions in market risks or counterparty credit risks, it is permitted to measure the fair value on a net basis. However, this must be
consistent with the manner in which market participants would price the net risk exposure at the measurement date.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Financial
assets and liabilities measured at fair value are shown in Note 22.3.

i) Investments accounted for using
the equity method

The Combined Groups interests in joint ventures and associates are recognized using the equity method.

Under the equity method, an investment in an associate or joint venture is initially recognized at cost. As of the acquisition date, the
investment is recognized in the statement of financial position based on the share of its equity that the Combined Groups interest represents in its capital, adjusted for, if appropriate, the effect of transactions with Combined Groups
entities, plus any goodwill generated in acquiring the entity. If the resulting amount is negative, zero is recorded for that investment in the statement of financial position, unless the Combined Group has a present obligation (either legal or
constructive) to support the investees negative equity situation, in which case a provision is recognized.

Goodwill from associates
or joint ventures is included in the carrying amount of the investment. It is not amortized but is subject to impairment testing as part of the overall investment carrying amount when impairment indicators exist.

Dividends received from these investments are deducted from the carrying amount of the investment, and any profit or loss obtained from them to
which the Combined Group is entitled based on its ownership interest is recognized under Share of profit (loss) of associates accounted for using equity method.

Appendix No. 3, Enersis Chile Combined Group Associated Companies and Joint Ventures, to these combined financial statements,
provides information about the relationship of Enersis with each of these entities.

j) Inventories

Inventories are measured at their weighted average acquisition cost or the net realizable value, whichever is lower.

k) Non-current assets held for sale and discontinued operations

The Combined Group classifies property, plant and equipment; intangible assets; investments accounted for using the equity method, joint
ventures, and disposal groups (a group of assets to be disposed of and the liabilities directly associated with those assets) as non-current assets held for sale, if, as of the date of the combined financial statements, the Combined Group has taken
active measures for their sale and estimates that such sale is highly probable.

Non-current assets held-for-sale or disposal groups are
measured at the lower of their carrying amount and fair value less costs of disposal. Depreciation and amortization on these assets cease when they meet the criteria to be classified as non-current assets held for sale.

Non-current assets or disposal groups classified as held for distribution to owners are measured at the lower of their carrying amount and
their fair value less costs to distribute.

Assets that are no longer classified as held for sale, or are no longer part of a disposal
group, are measured at the lower of their carrying amounts before being classified as held for sale less any depreciations, amortizations or revaluations that would have been recognized if they had not been classified as held for sale and their
recoverable amount at the date of subsequent decision to reclassify the non-current assets.

Non-current assets and the components of the
disposal groups classified as held for sale or held for distribution to owners are presented in the combined statement of financial position as a single line item within assets called Non-current assets or disposal groups held for sale or for
distribution to owners, and the respective liabilities are presented as a single line item within liabilities called Liabilities included in disposal groups held for sale or for distribution to owners.

The Combined Group classifies as discontinued operations those separate major lines of business that have been sold or disposed of, or are
classified as held for sale, including other assets that are part of the same coordinated sales or disposal plan. Similarly, entities that have been acquired exclusively with a view to resale are also considered discontinued operations.

The components of profit or loss after taxes from discontinued operations are presented as a single line item in the combined comprehensive
income statement as Income after tax from discontinued operations, including incremental taxes related to the spin-off transaction, once it becomes effective.

##### Table of Contents

l) Provisions

Provisions are recognized when the Combined Group has a present obligation (legal or constructive) as a result of a past event, it is probable
that the Combined Group will be required to settle the obligation, and a reliable estimate can be made of the amount of the obligation. The amount recognized as a provision is the best estimate of the consideration required to settle the present
obligation at the end of the reporting period, taking into account the risks and uncertainties surrounding the obligation. When a provision is measured using the cash flows estimated to settle the present obligation, its carrying amount is the
present value of those cash flows (when the effect of the time value of money is material).

Provisions are measured using the best
information available as of the date of issuance of the combined financial statements considering the consequences of the event causing the provision and are re-estimated at the end of each subsequent reporting period.

l.1) Provisions for post-employment benefits and similar obligations

Some of the combined entities have pension and similar obligations with their employees. These obligations, which can be defined benefits and
defined contributions, are basically formalized through pension plans, except for certain non-monetary benefits, mainly electricity supply commitments, which, due to their nature, have not been externalized and are covered by the related in-house
provisions.

For defined benefit plans, the cost of providing benefits is determined using the Projected Unit Credit Method, with actuarial
valuations being carried out at the end of each reporting period. Past service costs relating to changes in benefits are recognized immediately.

The defined benefit plan obligations in the statement of financial position represent the present value of the accrued obligations, adjusted,
once the fair value of the different plans assets has been deducted, if any.

For each of the defined benefit plans, any deficit
between the actuarial liability and the plan assets (if any) is recognized under line item Provisions for employee benefits within current and non-current liabilities in the combined statement of financial position.

Actuarial gains and losses arising in measurement of both the plan liabilities and the plan assets (if any, and excluding interest) are
recognized directly in other comprehensive income.

Contributions to defined contribution benefit plans are recognized as an expense in the
combined statement of comprehensive income when the employees have rendered their services.

m) Translation
of foreign currency balances

Transactions carried out by each entity in a currency other than its functional currency are recognized
using the exchange rates prevailing as of the date of the transactions. During the year, any differences that arise between the prevailing exchange rate at the date of the transaction and the exchange rate as of the date of collection or payment are
recognized as Foreign currency exchange differences in the combined statement of comprehensive income.

Likewise, at the end of
each reporting period, receivable or payable balances denominated in a currency other than each entitys functional currency are translated using the closing exchange rate. Any differences are recorded as Foreign currency exchange
differences in the combined statement of comprehensive income.

The Combined Group has established a policy to hedge the portion of
revenue from its combined entities that is directly linked to variations in the U.S. dollar, through obtaining financing in such currency. Exchange differences related to this debt, which is regarded as the hedging instrument in cash flow hedge
transactions, are recognized, net of taxes, in other comprehensive income and are accumulated in an equity reserve and reclassified to profit or loss when the hedged cash flows impact profit or loss. This term has been estimated at five years.

n) Current/non-current classification

In these combined statements of financial position, assets and liabilities expected to be recovered or settled within twelve months are
presented as current items, except for post-employment and other similar obligations. Those assets and liabilities expected to be recovered or settled in more than twelve months are presented as non-current items. Deferred income tax assets and
liabilities are classified as non-current.

When the Combined Group have any obligations that mature in less than twelve months but can be
refinanced over the long term at the Combined Groups discretion, through unconditionally available credit agreements with long-term maturities, such obligations are classified as long-term liabilities.



F-31

##### Table of Contents

o) Income taxes

Income tax expense for the period is determined as the sum of current taxes from the Combined Groups different combined entities and
results from applying the tax rate to the taxable income for the period, after permitted deductions have been made, plus any changes in deferred tax assets and liabilities and tax credits, both for tax losses and deductions. Differences between the
carrying amount and tax basis of assets and liabilities generate deferred tax assets and liabilities, which are calculated using the tax rates expected to apply when the assets and liabilities are realized or settled, based on tax rates that have
been enacted or substantively enacted by the end of the reporting period.

Deferred tax assets are recognized for all deductible temporary
differences, tax losses and unused tax credits to the extent that it is probable that sufficient future taxable profits exist to recover the deductible temporary differences and make use of the tax credits. Such deferred tax asset is not recognized
if the deductible temporary difference arises from the initial recognition of an asset or liability that:



| |  |  | Did not arise from a business combination, and
| | - |  | ----------------------------------------------



| |  |  | At initial recognition affected neither accounting profit nor taxable profit (loss).
| | - |  | ------------------------------------------------------------------------------------

With
respect to deductible temporary differences associated with investments in combined entities, associates and joint arrangements, deferred tax assets are recognized only to the extent that it is probable that the temporary differences will reverse in
the foreseeable future and taxable profits will be available against which the temporary differences can be utilized.

Deferred tax
liabilities are recognized for all temporary differences, except those derived from the initial recognition of goodwill and those that arose from investments in combined entities, associates and joint ventures in which the Combined Group can control
their reversal and where it is probable that they will not be reversed in the foreseeable future.

Current tax and changes in deferred tax
assets or liabilities are recorded in profit or loss or in equity, depending on where the gains or losses that triggered these tax entries have been recognized.

Any tax deductions that can be applied to current tax liabilities are credited to earnings within the line item Income tax
expenses, except when doubts exist about their tax realization, in which case they are not recognized until they are effectively realized, or when they correspond to specific tax incentives, in which case they are recorded as government
grants.

At the end of each reporting period, the Combined Group reviews the deferred taxes assets and liabilities recognized, and makes,
if any, necessary corrections based on the results of this analysis.

Deferred tax assets and deferred tax liabilities are offset in the
combined statement of financial position if has a legally enforceable right to set off current tax assets against current tax liabilities, and only when the deferred taxes relate to income taxes levied by the same taxation authority.

p) Revenue and expense recognition

Revenue is recognized when the gross inflow of economic benefits arising in the course of the Combined Groups ordinary activities in the
period occurs, provided that this inflow of economic benefits results in an increase in total equity other than increases relating to contributions from equity participants and such benefits can be measured reliably.

Revenues and expenses are recognized on an accrual basis and depending on the type of transaction; the following criteria for recognition are
taken:



| |  |  | Generation of electricity: Revenue is recognized based on physical delivery of energy and power, at prices established in the respective contracts, at prices stipulated in the electricity market by applicable
regulations or at marginal cost determined on the spot market, as the case. This revenue includes an estimate of the service provided and not billed until the closing date (see Note 2.3 and 27).
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Distribution of electricity: Revenue is recognized based on the amount of energy supplied to customers during the period, at prices established in the respective contracts or at prices stipulated in the
electricity market by applicable regulations, as appropriate. This revenue includes an estimate of the energy supplied but not yet billed and for which the customers meters have not been read yet (see Note 2.3 and 27).
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Revenue from rendering of services is only recognized when it can be estimated reliably, by reference to the stage of completion of the service
rendered at the date of the statement of financial position. When the outcome of a transaction involving the rendering of services cannot be estimated reliably, revenue is recognized only to the extent of the expenses recognized that are
recoverable. (See Note 27)



F-32

##### Table of Contents

Revenue from sales and goods is recognized based on the economic substance of the transaction and
are recognized when all and each of the following conditions are met:



| |  |  | the entity has transferred to the buyer the significant risks and rewards of ownership of the goods;
| | - |  | ----------------------------------------------------------------------------------------------------



| |  |  | the entity retains neither continuing managerial involvement to the degree usually associated with ownership nor effective control over the goods sold;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the amount of revenue can be measured reliably;
| | - |  | -----------------------------------------------



| |  |  | it is probable that the economic benefits associated with the transaction will flow to the entity; and
| | - |  | ------------------------------------------------------------------------------------------------------



| |  |  | the costs incurred or to be incurred in respect of the transaction can be measured reliably.
| | - |  | --------------------------------------------------------------------------------------------

Revenue is measured at the fair value of the consideration received or receivable that gives rise to the revenue.

In arrangements under which the Combined Group will perform multiple revenue-generating activities (multiple-element arrangement), the
recognition criteria are applied to the separately identifiable components of the transaction in order to reflect the substance of the transaction or to two or more transactions together when they are linked in such a way that the commercial effect
cannot be understood without reference to the series of transactions as a whole.

The Combined Group excludes from revenue those gross
inflows of economic benefits it receives when it acts as an agent or commission agent on behalf of third parties, and only recognizes as revenue economic benefits received for its own activity.

When goods or services are exchanged or swapped for goods or services of a similar nature and value, the exchange is not regarded as a
revenue-generating transaction.

The Combined Group recognizes the net amount of non-financial asset purchases or sale contracts that are
settled for a net amount of cash or through some other financial instruments. Contracts entered into and maintained for the purpose of receiving or delivering these non-financial assets are recognized on the basis of the contractual terms of the
purchase, sale, or usage requirements expected by the entity.

Financial income (expense) is recognized using the effective interest rate
applicable to the outstanding principal over the repayment period.

Expenses are recognized on an accruals basis, immediately in the event
of expenditures that do not generate future economic benefits or when they do not meet the requirements for recording them as assets.

q) Dividends

Article 79 of the Chilean Companies Act establishes that, unless unanimously agreed otherwise by the shareholders of
all issued shares, listed corporations must distribute a cash dividend to shareholders on an annual basis, pro rata to the shares owned or the proportion established in the companys by-laws if there are preferred shares, of at least 30% of net
income for each year, except when accumulated losses from prior years must be absorbed.

As it is practically impossible to achieve a
unanimous agreement not to approve the mandatory dividend, given Enersis highly fragmented share capital. At the end of each reporting period the amount of the minimum statutory dividend obligation to its shareholders is determined, net of
interim dividends approved during the fiscal year, and then accounted for in Trade and other current payables and Accounts payable to related companies, as appropriate, and recognized in Equity.

Interim and final dividends are deducted from Equity when approved by the competent body, which in the first case is normally the Board of
Directors and in the second case is the shareholders as agreed at an Ordinary Shareholders Meeting.

r) Share issuance costs

Capital issuance costs, only when represents incremental expenses directly attributable to the transaction, are recognized directly in equity
as a deduction from Allocated capital, net of any applicable taxes. If the allocated capital account has a zero balance or if the costs described exceed the balance, they are recognized in Other reserves.



|4. | SECTOR REGULATION AND ELECTRICITY SYSTEM OPERATIONS.
|-- | ----------------------------------------------------

4.1 Regulatory framework:

The electricity sector is regulated by the General Law of Electrical Services (Chilean Electricity Law), also known as DFL No. 1
of 1982, of the Ministry of Mining, whose compiled and coordinated text was established in DFL No. 4 issued in 2006 by the Ministry of Economy (the Electricity Law), as well as by an associated Regulation (D.S. No. 327 issued in 1998).
Three government bodies are primarily responsible for enforcing this law: the National Energy Commission (CNE), which has the



F-33



---

##### Table of Contents

authority to propose regulated tariffs (node prices) and to draw up indicative plans for the construction of new generating units; the Superintendency of Electricity and Fuels (SEF), which
supervises and oversees compliance with the laws, regulations, and technical standards that govern the generation, transmission, and distribution of electricity, as well as liquid fuels, and gas; and the Ministry of Energy, which is responsible for
proposing and guiding public policies on energy matters. It also oversees the SEF, the CNE, and the Chilean Commission for Nuclear Energy (ChCNE), thus strengthening coordination and allowing for an integrated view of the energy sector. The Ministry
of Energy also includes the Agency for Energy Efficiency and the Center for Renewable Energy, (Centro de Energías RenovablesCER), which in November 2014 was replaced by the National Center for Innovation and Development of
Sustainable Energy (Centro Nacional para la Innovación y Fomento de las Energías SustentablesCIFES). The Chilean Electricity Law has also established a Panel of Experts whose main task is to resolve potential discrepancies
among the players in the electricity market, including electricity companies, system operators, regulators, etc.

From a physical
viewpoint, the Chilean electrical sector is divided into four electrical grids: the Sistema Interconectado Central (SIC), the Sistema Interconectado del Norte Grande (SING), and two separate medium-size grids located in southern Chile,
one in Aysén and the other in Magallanes. The SIC, the main electrical grid, runs 2,400 km longitudinally and connects the country from Taltal in the north to Quellon, on the island of Chiloe in the south. The SING covers the northern part of
the country, from Arica down to Coloso, covering a length of some 700 km. A law was passed on January 8, 2014, which will allow the SIC to be connected to the SING.

The electricity industry is organized into three business segments: generation, transmission, and distribution, all operating in an
interconnected and coordinated manner, and whose main purpose is to supply electrical energy to the market at minimum cost while maintaining the quality and safety service standards required by the electrical regulations. As essential services, the
power transmission and distribution businesses are natural monopolies; these segments are regulated as such by the electricity law, which requires free access to networks and regulates rates.

Under the Chilean Electricity Law, companies engaged in generation and transmission on an interconnected electrical grid must coordinate their
operations through a centralizing operating agent, the Centro de Despacho Económico de Carga (CDEC), in order to operate the system at minimum cost while maintaining a reliable service. For this reason, the CDEC plans and operates the
system, including the calculation of the so-called marginal cost, which is the price assigned to energy transfers among power generating companies.

Therefore, a companys decision to generate electricity is subject to the CDECs operation plan. On the other hand, each company is
free to decide whether to sell its energy to regulated or unregulated customers. Any surplus or deficit between a companys sales to its customers and its energy supply is sold to, or purchased from, other generators at the spot market price.

A power generating company may have the following types of customers:

(i) Distribution companies that supply power to regulated customers: This distribution is to residential and commercial consumers and
small and medium-size businesses with a connected capacity equal to or less than 500 kW located in the concession area of a distribution company. Until January 2015, customers consuming between 500kW and 2,000 kW may choose to be regulated or
unregulated customers. On January 29, 2015, it was published in the Official Gazette an amendment to the law increasing the upper threshold from 2,000kW to 5,000kW. A summarized description of the scope of the amendments to the law is given
below.

Until 2009, the transfer prices between generators and distribution companies for supplying power to regulated customers were
capped at a maximum value called the node price, which is regulated by the Ministry of Energy. Node prices are set every six months, in April and October, based on a report prepared by the CNE that takes into account projections of expected marginal
costs in the system over the next 48 months for the SIC and 24 months for the SING. Beginning in 2010, and as the node price contracts begin to expire, the transfer prices between generators and distributors are being replaced by the results of
regulated bidding processes, with a price cap set by the authority every six months.

(ii) Unregulated customers: Those customers,
mainly industrial and mining companies, with a connected capacity of over 5,000 kW. These consumers can freely negotiate prices for electrical supply with generators and/or distributors. Customers with capacity between 500 and 5,000 kW, have the
option to contract energy at prices agreed upon with their suppliers or be subject to regulated prices, with a minimum term of at least four years under each pricing system. As previously discussed, the 5,000 kW threshold became effective beginning
on January 30, 2015.

(iii) Spot market: This represents energy and capacity transactions among generating companies that
result from the CDECs coordination to keep the system running as economically as possible, where the surpluses (deficits) between a generators energy supply and the energy it needs to comply with business commitments are transferred
through sales (purchases) to (from) other generators in the CDEC. In the case of energy, transfers are valued at the marginal cost, while node prices for capacity are set every semester by the regulators.



F-34

##### Table of Contents

In Chile, the capacity that must be paid to each generator depends on an annual calculation
performed by the CDEC to determine the firm capacity of each power plant, which is not the same as the dispatched capacity.

Beginning in
2010 with the enactment of Law 20,018, distribution companies must have sufficient supply permanently available to cover their entire demand projected for a period of three years; to do so, they must carry out long-term public bidding processes.
This period of three years has been changed to five years, following the legislative amendment published in January 2015.

On May 15,
2014, the Minister of Energy presented the Energy Agenda, a document outlining general guidelines for the energy policy of the new government.

On December 29, 2014 a Tax Reform was published in the Official Gazette, which emphasizes the creation of so-called green tax to be levied
on air emissions of particulate matter (PM), nitrogen oxides (NOx), sulfur dioxide (SO2) and carbon dioxide (CO2). The tax will be US$5/ton for CO2 emissions.

On January 29, 2015, Law 20,805 was published in the Official Gazette, incorporating a legal amendment to the energy bidding processes for
consumption of regulated customers. Among the main changes incorporated through this amendment are the increased participation of the CNE in the bidding processes; the increase from three to five years for the anticipated bidding announcements; the
incorporation of a reserved price as a limit price for each bid; the chance for a bidder to delay the energy supply in case of force majeure; the increase of the duration of the supply contract up to 20 years; the incorporation of short-term
biddings; the treatment for energy without contract; and the increase in the upper threshold to qualify as regulated customer from 2,000 to 5,000 kW.

Non-Conventional Renewable Energy

In Chile, Law 20,257 was enacted in April of 2008 to encourage the use of Non-Conventional Renewable Energy (NCRE). The principal aspect of
this law is that at least 5% of the energy sold by generation companies to their customers must come from renewable sources between years 2010 and 2014. This requirement progressively increases by 0.5% from year 2015 until 2024, when a 10% renewable
energy requirement will be reached. This law was amended in 2013 by Law 20,698, dubbed the 20/25 law, as it establishes that by 2025, 20% of power supplied will be generated by NCRE. It does not change the previous laws plan for
supplying power under agreements in effect in July 2013.

Limits on integration and concentration

Chile has legislation in effect that defends free competition and, together with specific regulations that apply to the electricity market,
defines criteria to avoid certain levels of economic concentration and/or abusive market practices.

In principle, the regulators allow the
participation of companies in different activities (e.g. generation, distribution, and commercialization) as long as there is an adequate separation of each activity, for both accounting and company purposes. Nevertheless, most of the restrictions
imposed involve the transmission sector mainly due to its nature and to the need to guarantee adequate access to all agents. In Chile, there are specific restrictions if generation or distribution companies want to become majority shareholders in
transmission companies.

Regarding concentration in a specific sector, while there are regulations on free competition, there are no
specific quantitative limits on vertical or horizontal integration. However, the General Law on Electrical Services provides that companies that operate on or have ownership in the Trunk Transmission Systems cannot engage in, either directly or
indirectly, activities that are in any way involved in the business of power generation or distribution.

Market for unregulated
customers

In Chile, distributing companies can supply their customers under regulated or freely-agreed conditions. For clients
purchasing more than 500kW and less than 5,000 Kw may choose between the regulated and unregulated markets. Clients purchasing more than 5,000 kW are required to be categorized as unregulated customers. The 5,000 kW threshold became effective
beginning on January 30, 2015. Clients purchasing less than 500 kW are regulated customers and such threshold is applied if energy is purchased from renewable sources, for which the government provide incentives through a discount on tolls.

4.2 Tariff Revisions:

General Aspects

In Chile,
selling prices charged to clients are based on the purchase price paid to generators plus a component associated with the value added in distribution. Regulators set this value periodically through reviews of distribution tariffs. As a result,
distribution is essentially a regulated activity.

The Distribution Value Added (VAD) is established every four years. For this, the local
regulator, (the CNE) classifies companies by typical areas that group together companies with similar distribution costs. A distribution companys return on investment depends on the companys performance compared to model company
standards defined by the regulator. On April 2, 2013, the Energy Ministry published Tariff Decree No. 1T in the Official Gazette. This was made retrospectively to November 4, 2012 and will remain in effect until November 3, 2016.
The next tariff-setting process will take place in 2016 and will cover the period November 2016 to November 2020.

Decree No. 14,
which established the subtransmission tolls for this segment for 2011-2014 was published in the Official Gazette on April 9, 2013. On January 29, 2015, the Energy Ministry extends the term of the Decree until 2015, as it is state on
transitory articles on Law 20.805. The Average Node Price Decrees transfer these tolls to final customers, as they are part of distribution companys costs.

On January 27, 2015, the Energy Ministry published in the Official Gazette, Decree No. 9T, which established the node prices for
energy that will be retrospectively applied beginning on May 1, 2014.

On May 12, 2015, the Energy Ministry published in the
Official Gazette, Decrees No.2T and 3T, which established the node prices for energy supply that will be retrospectively applied beginning on September 1 and October 1, 2014, respectively.

On May 22, 2015, the Energy Ministry published in the Official Gazette, Decree No. 9T, which established the node prices for energy
supply that will be retrospectively applied beginning on November 1, 2014.

On June 23, 2015, the Energy Ministry published in
the Official Gazette, Decree No.12T, which established the node prices for energy supply that will be retrospectively applied beginning on January 1, 2015.

On August 4, 2015, the Energy Ministry published in the Official Gazette, Decree No. 15T, which established the node prices for
energy supply that will be retrospectively applied beginning on February 1, 2015.

On November 4, 2015, the Energy Ministry
published in the Official Gazette, Decree No. 16T, which established the node prices for energy supply that will be retrospectively applied beginning on April 1, 2015.

On December 26, 2015, the Energy Ministry published in the Official Gazette, Decree No.21T, which established the node prices for energy

|5. | NON-CURRENT ASSETS OR GROUPS OF ASSETS FOR DISPOSAL CLASSIFIED AS HELD FOR SALE.
|-- | --------------------------------------------------------------------------------

In
December 2014, Empresa Nacional de Electricidad S.A. and its combined entity Compañía Eléctrica de Tarapacá SA signed a contract to sell all their shares in Sociedad Concesionaria Túnel El Melón S.A. to
Temsa Private Investment Fund. Such contract established a number of conditions, which were not fulfilled at the end of 2014, preventing the closure of the sale. The sale was finalized on January 9, 2015. (See Note 32)

Túnel El Melón S.A is a private corporation whose purpose is the construction, maintenance and operation of the public work
called the El Melón Tunnel and the provision of ancillary services authorized by the Ministry of Public Works (MOP).

El
Melón Tunnel is an alternative route to the road that climbs the El Melon pass, which is located between 126 and 132 kilometers north of Santiago on Route 5. This is the main highway linking the country from Arica to Puerto Montt.

As described in Note 3.k), non-current assets and groups of assets held for sale have been recorded at the lower of their carrying amount and
fair value less costs of disposal.

The main items of assets, liabilities and cash flows held for sale as of December 31, 2014, are as
follows:

|6. | BUSINESS COMBINATION  ACQUISITION OF GASATACAMA.
|-- | -------------------------------------------------

On April 22, 2014, the
Combined Group through its combined entity Endesa Chile acquired the remaining 50% ownership interest in Inversiones GasAtacama Holding Limitada (hereinafter GasAtacama) that was owned by Southern Cross Latin America Private Equity Fund
III L.P. (hereinafter Southern Cross) at that time.

Consequently, the Combined Group now holds 100% of control over GasAtacama
which at the same time is the owner of (i) the Atacama Plant, a 780 MW capacity combined cycle thermal power plant fired by natural gas or diesel oil located in the north of Chile; (ii) the 940 km Atacama Pipeline that runs between Coronel
Cornejo in Argentina and Mejillones in Chile; and (iii) the 223 km Taltal Pipeline between Mejillones and Paposo.

Upon obtaining
control of GasAtacama, the Combined Groups total generation capacity in Chiles northern grid (the Sistema Interconectado del Norte Grande, or SING) reached 1,000 MW, and it is expected to enable us to satisfy greater industrial,
residential and mining demand through a competitively priced energy supply with a low environmental impact.

GasAtacama acquisition was
recognized using the accounting criteria for business combinations achieved in stages as detailed in Note 2.6.1.

Since the date of
acquisition, GasAtacama has contributed ThCh$113,074,006 in revenues and ThCh$33,443,547 in income before tax to the Combined Groups results. Had the acquisition taken place on January 1, 2014, it is estimated that these amounts would
have been ThCh$179,474,707 in revenues and ThCh$41,772,291 in income before tax for the year ended December 31, 2014.

a)
Consideration transferred

The following table summarizes the fair value of each type of consideration transferred in connection with
the GasAtacama acquisition:



|                                                                                     |  |       |             |

|Total price paid                                                                     |  |       | 174,028,622 |

|                                                                                     |  |       |             |  
|Total consideration paid in cash (Note 8)                                            |  |       | 157,958,101 |  
|                                                                                     |  |       |             |  



| | (i) | The total consideration transferred was ThCh$174,028,622 and included the assignment of rights to collect on an outstanding loan of ThCh$16,070,521 owed by Pacific Energy Sub Co. (a subsidiary of Southern Cross) to
Atacama Finance Co. (a subsidiary of GasAtacama).
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

b) Acquisition-related costs

Endesa Chile incurred costs for ThCh$23,543 in financial advisory fees related to the acquisition of Inversiones GasAtacama Holding Limitada.
These costs have been recognized in 2014 under the line item Other expenses in the combined statements of comprehensive income.

|Deferred tax liabilities                           |  |            | (28,923,167 | )
|Other liabilities                                  |  |            | (10,874,817 | )

No risk of default is expected for the gross amount of trade and other receivables.

Given the nature of GasAtacamas business and assets, the fair value of the assets acquired and liabilities assumed was measured using the
following valuation approaches:

i. The market approach using the comparison method, based on quoted market prices for identical or
comparable items when available.

ii. The cost approach or depreciated replacement cost, which reflects adjustments for physical
deterioration and functional and economic obsolescence.

iii. The income approach, which uses valuation techniques that convert future
amounts (such as cash flows or income and expenses) into a single current amount (that is, discounted). The fair value measurement reflects current market expectations for those future amounts.

Reconciliation of values

Finally, the fair values were determined from an assessment and reconciliation of the results obtained from the methods selected, based on the
nature of each asset acquired and liability assumed.

d) Goodwill

|Total consideration paid                            |  |       | 157,958,101  |  
|Fair value of pre-existing interest in the acquiree |  |       | 157,147,000  |  
|Fair value of identifiable net assets acquired      |  |       | (296,367,364 | )
|                                                    |  |       |              |  
|Goodwill (See Note 16)                              |  |       | 18,737,737   |  

The goodwill is attributable primarily to the value of the synergies expected to be obtained by integrating
GasAtacama into the Combined Group. These synergies include reduced administrative, research and structure costs, which could be absorbed by Endesa Chile.

e) Remeasurement of pre-existing interest and currency translation differences

The remeasurement of the fair value of Endesa Chiles pre-existing 50% equity interest in GasAtacama resulted in a gain of ThCh$21,546,320
(See Note 32). The gain recognized was the positive difference between the acquisition-date fair value of the pre-existing equity interest of ThCh$157,147,000, and the carrying amount of the investment accounted for using the equity method at the
acquisition date of ThCh$135,600,682.

In addition, the exchange differences on translation of the pre-existing equity interest
accumulated in the equity of the Combined Group at the acquisition date, were reclassified to profit or loss resulting in a gain of ThCh$21,006,456. (See Note 32)

Both amounts have been recorded in 2014, in the caption Other gains (losses) in the combined statement of comprehensive income.



|7. | CAPITAL INCREASE.
|-- | -----------------

The Enersis allocated capital increase approved by the Extraordinary
Shareholders Meeting on December 20, 2012, was completed in the first quarter of 2013; all of the allocated shares were subscribed (see Note 26.1.1).

This capital increase amounted to ThCh$2,845,858,393. Of this, 60.62% of the shares were subscribed by Endesa S.A., Enersis parent
company located in Spain, and were paid for with its investments in Latin America valued at ThCh$1,724,400,000. The remaining shares were subscribed and paid with non-controlling interests of Enersis via cash payments of ThCh$1,121,458,393, which
included an Allocated capital of ThCh$1,460,503. This capital increase has been reflected in the combined statement of changes in equity in relation to the contributions in kind of additional interests of Endesa S.A.s in certain entities in
Chile for ThCh$1,092,347,262.

The amounts included in financial assets held to maturity and
financial assets at fair value with change in profit or loss correspond mainly to time deposits and other highly liquid investments that are readily convertible to cash and subject to a low risk of changes in value, but that do not
fulfill the definition of cash equivalent as defined in Note 3.g.2 (e.g. with maturity over 90 days from time of investment).

Write-offs for past due receivables

Past due receivables are written off once all collection procedures and legal proceedings have been exhausted and the debtors
insolvency has been demonstrated. In our power generation business, this process normally takes at least one year. In our distribution business the process takes at least twenty four months. Overall, the risk of writing off our trade receivables is
limited (see Notes 3.g.3, 21.5 and Appendices 6 and 6.1).

| | (3) | In 2015, the assessment of the functional currency of Inversiones GasAtacama Holding Ltda. was revised and we determined the Chilean Peso as its functional currency. Our decision to change the functional currency was
made considering that upon integration of operations of this entity it became an extension of its immediate parent Endesa Chile, as such, have the same functional currency, that is, the Chilean peso. The change was applied prospectively.

e) Other information

i) As of December 31, 2015 and 2014, the Combined Group had contractual commitments for the acquisition of property, plant and equipment
amounting to ThCh$297,847,453 and ThCh$170,911,479, respectively.

ii) As of December 31, 2015 and 2014, the Combined Group does not
have property, plant and equipment pledged as security for liabilities.

iii) The Combined Group and its combined entities have insurance
policies for all risks, earthquake and machinery breakdown and damages for business interruption with a 1,000 million limit in the case of generating companies and a 50 million limit for distribution companies, including
business interruption coverage. Additionally, the Combined Group has Civil Liability insurance to meet claims from third parties with a 500 million limit. The insurance premiums associated with these policies are presented proportionally
for each company in the caption Prepaid expenses.

iv) The condition of certain assets of our subsidiary Endesa Chile changed,
primarily works and infrastructure for facilities built to support power generation in the SIC grid in 1998, due primarily to the installation in the SIC of new thermoelectric plants, the arrival of LNG, and new other projects. As such, a new supply
configuration for the upcoming years, in which it is expected that these facilities will not be used. Therefore, in 2009, the Company recognized an impairment loss of ThCh$43,999,600 for these assets, which is still has not reversed.

v) On October 16, 2012, Endesa Chile began the collection process on all of the bank performance bonds guaranteeing compliance with the
works and correct, timely execution of these works as specified in the agreement Bocamina Thermal Plant Expansion Project, contract ACP-003.06. This is a turnkey project for a 350 MW coal-fired thermal generation plant (the
contract) signed on July 25, 2007 between Empresa Nacional de Electricidad S.A. (the owner) and the consortium consisting of (i) the Chilean company Ingeniería y Construcción Tecnimont Chile y
Compañía Limitada; (ii) the Italian company Tecnimont SpA; (iii) the Brazilian company Tecnimont do Brasil Construcao e Administracao de Projetos Ltda; (iv) the Slovakian company Slovenske Energeticke Strojarne a.s.
(SES); and (v) the Chilean company Ingeniería y Construcción SES Chile Limitada; (all referred to collectively as the Contractor or the Consortium).

These performance bonds amounted to US$74,795,164.44 and UF 796,594.29 (approximately
US$38,200,000). As of December 31, 2012, US$93,992,554 of these bonds was collected. Collection made on these bank performance bonds reduced the capitalized cost overruns incurred by the company due to breach of contract.

On October 17, 2012, Endesa Chile filed an arbitration request with the International Chamber of Arbitration of Paris in order to enforce
the rights conferred upon it under the Contract. On December 29, 2014, Endesas Board of Directors accepted and approved an agreement with the Consortium that finalizes the arbitration process and grants full reciprocal settlement of the
obligations. Consequently, as a result of final agreement reached at the end of 2014, Endesa Chiles acquisition costs of the plant increased by US$125 million (ThCh$75,843,750 approximately) which were recognized as part of the acquisition
cost of property, plant and equipment. The payment of these costs was made on April 6, 2015.

vi) At the end of 2012, our combined
entity Compañía Eléctrica Tarapacá S.A., whose assets and liabilities as of December 31, 2015 have been classified as non-current assets held for distribution to owners, recognized an impairment loss of
ThCh$12,578,098, to adjust the carrying amount of certain specific assets operating in the SING grid to its recoverable amount.

At the
closing of 2015, were approved certain regulatory developments to the Chilean energy industry, which after being evaluated by the Company, resulted in the identification of a new single CGU for all generation assets in Chile. The analysis takes into
account the fact that Endesa Chile, a discontinued operation as of December 31, 2015, performs an optimization and management of all its assets related to its generation business, it has a centralized trade policy, with sales contracts agreed
at company level and not assigned to power plants. Therefore, generation of cash flows depends on all the assets as a whole.

Previously,
the company identified a CGU for the assets operating in the SIC grid and another one for the assets operating in the SING, under the consideration that there were two separate markets. The new scheme, approved in 2015, posed by the interconnection
of SIC and SING, unifies markets and considers a single determination of prices, which was illustrated by latest bids for energy supply to regulated customers.

Therefore, these new conditions indicated that the recognized impairment loss mentioned above has been reversed. This was based, inter alia, on
the generation of additional value by the interconnection project between the SIC and SING which is expected to be operational in 2019, by improved utilization of reserves, by expanding the potential market for specific impaired assets and
decreasing overall risk of the portfolio. The effects of the interconnection are considered in the five-year projections used by the company to perform impairment tests (see Note 3.e).

vii) At the end of 2014, Endesa Chile S.A. recognized an impairment loss of ThCh$12,581,947 related to the Punta Alcalde project. This
impairment loss was triggered because the current definition of the project is not fully aligned with the strategy that the Company is reformulating, particularly, with regard to technological leadership, and to community and environmental
sustainability. Endesa Chile has decided to suspend the project pending clarification of its profitability (see Note 3.e).

viii) In line
with its sustainability strategy and in order to develop community relationships, Endesa Chile has decided to research new design alternatives for the Neltume project, in particular regarding the issue of the discharge of Lake Neltume, which has
been raised by the communities in the various instances of dialogue.

To start a new phase of research of an alternative project, which
includes the discharge of water on the Fuy River in late December 2015, the Company withdrew the Environmental Impact Study. This decision applies only to the portion of the Neltume project related to the power plant and not to portion related to
the transmission project, which continues its course on handling in the Environmental Assessment Service.

As a result of the above, as of
December 31, 2015, Endesa Chile recognized a loss of ThCh$2,706,830, associated with the write down of certain assets related to Environmental Impact Study, which has been withdrawn and to other studies directly linked to the old design of
assets.

ix) As of December 31, 2015, Endesa Chile recognized an impairment loss of ThCh$2,522,445 related to the wind project Waiwen.
This loss was a result of new assessment of the feasibility of the project performed by the Company and a conclusion that, under existing conditions to date, its profitability is uncertain.

Recovery of deferred tax assets will depend on whether sufficient tax
profits will be obtained in the future. The Combined Group believes that the future profit projections for its combined entities will allow these assets to be recovered.

b. As of December 31, 2015, the Combined Group does not have unrecognized deferred tax assets related to tax loss carryforwards. As
of December 31, 2014, the Combined Group has unrecognized deferred tax assets related to tax loss carryforwards totaling ThCh$351,900, respectively. See Note 3.p.

As of December 31, 2015, the Combined Group recognized a deferred tax liability of ThCh$7,350,754 in relation with the existing taxable
temporary difference arising from the investment in the subsidiaries that Endesa Chile and Chilectra Chile hold in Peru, considering that, as part of the corporate reorganization, said investments are to be transferred to Endesa Américas S.A.
and Chilectra Américas S.A., respectively. (See Note 40).

The Combined Group has not recognized deferred tax liabilities for
taxable temporary differences associated with investment in combined entities and joint ventures, as it is able to control the timing of the reversal of the temporary differences and considers that it is probable that such temporary differences will
not reverse in the foreseeable future. As of December 31, 2015 and 2014, the aggregate of taxable temporary differences associated with investments in combined entities and joint ventures for which deferred tax liabilities have not been
recognized totaled ThCh$855,628,553 and ThCh$426,167,022, respectively. Additionally, the Combined Group has not recognized deferred tax asset for deductible temporary differences which as of December 31, 2015 and 2014, totaled ThCh$463,809,815
and ThCh$966,314,793, respectively, as it is not probable that sufficient future taxable profits exist to recover such temporary differences.

The Combined Group companies are potentially subject to income tax audits by the Chilean tax regulator and are limited to three tax years after
which tax audits over those years can no longer be performed. Tax audits by nature are often complex and can require several years to complete. The tax years potentially subject to examination are 2012 through 2014.

Given the range of possible interpretations of tax standards, the results of any future inspections carried out by Chilean tax authority for
the years subject to audit can give rise to tax liabilities that cannot currently be quantified objectively. Nevertheless, management estimates that the liabilities, if any, that may arise from such tax audits, would not significantly impact the
Combined Groups future results.

c. In Chile, Law No. 20,780 was published in the Official Gazette on September 29, 2014. It
changes the income tax system and other taxes, by replacing the current tax system in 2017 with two alternative tax systems: the attributed income system and partially integrated system.

This Law gradually increases the rate of income tax on corporate income. Thus, it will increase to 21% in 2014, to 22.5% in 2015 and to 24% in
2016. As from 2017 taxpayers choosing the attributed income system will be subject to a rate of 25%, while companies choosing the partially integrated system will be subject to a rate of 25.5% in 2017 and 27% in 2018.

Furthermore, this Law establishes that the partially integrated system will apply by default to open stock companies, unless a future
Extraordinary Shareholders Meeting agrees to adopt the attributed income system.

The Combined Group assumes that, since an
Extraordinary Shareholders Meeting has not agreed to adopt the alternative system, the partially integrated system applies by default. Therefore, changes in deferred tax assets and liabilities as a direct effect of the increase in the
corporate income tax rate have been recognized in profit or loss. Specifically, for the year ended December 31, 2014 the net charge against income was a loss of ThCh$66,669,816.

|21. | RISK MANAGEMENT POLICY.
|--- | -----------------------

The Combined Groups companies are exposed to certain
risks that are managed by systems that identify, measure, limit concentration of, and monitor these risks.

The main principles in the
Combined Groups risk management policy include the following:



| |  |  | Compliance with good corporate governance standards.
| | - |  | ----------------------------------------------------



| |  |  | Strict compliance with all the Combined Groups internal policies.
| | - |  | ------------------------------------------------------------------



| |  |  | Each business and corporate area determines:
| | - |  | --------------------------------------------



| | I. | The markets in which it can operate based on its knowledge and ability to ensure effective risk management;
| | -- | -----------------------------------------------------------------------------------------------------------



| | II. | Criteria regarding counterparts;
| | --- | --------------------------------



| | III. | Authorized operators.
| | ---- | ---------------------



| |  |  | Business and corporate areas establish their risk tolerance in a manner consistent with the defined strategy for each market in which they operate.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | All of the operations of the businesses and corporate areas are conducted within the limits approved for each case.
| | - |  | -------------------------------------------------------------------------------------------------------------------



| |  |  | Businesses, corporate areas, lines of business and companies design the risk management controls necessary to ensure that transactions in the markets are conducted in accordance with the Enersis Chiles policies,
standards, and procedures.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

21.1 Interest rate risk

Changes in interest rates affect the fair value of assets and liabilities bearing fixed interest rates, as well as the expected future cash
flows of assets and liabilities subject to floating interest rates.

The objective of managing interest rate risk exposure is to achieve a
balance in the debt structure to minimize the cost of debt with reduced volatility in profit or loss.

Depending on the Combined
Groups estimates and on the objectives of the debt structure, hedging transactions are performed by entering into derivatives contracts that mitigate interest rate risk. Derivative instruments currently used to comply with the risk management
policy are interest rate swaps to set floating rate at fixed rate.

21.2 Exchange rate risk

Exchange rate risks involve basically the following transactions:



| |  |  | Debt taken on by the Combined Groups companies that is denominated in a currency other than that in which its cash flows are indexed.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Payments to be made for the acquisition of project-related materials and for corporate insurance policies in a currency other than that in which its cash flows are indexed.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Income in the Combined Group companies directly linked to changes in currencies other than that of its cash flows.
| | - |  | ------------------------------------------------------------------------------------------------------------------

In order to mitigate foreign currency risk, the Combined Groups foreign currency risk management policy is based on cash flows and
includes maintaining a balance between U.S. dollar flows and the levels of assets and liabilities denominated in this currency. The objective is to minimize the exposure to variability in cash flows that are attributable to foreign exchange risk.

The hedging instruments currently being used to comply with the policy are currency swaps and forward exchange contracts. In addition, the
policy seeks to refinance debt in the functional currency of each of the Combined Groups companies.

21.3 Commodities risk

The Combined Group has a risk exposure to price fluctuations in certain commodities, basically due to:



| |  |  | Purchases of fuel used to generate electricity.
| | - |  | -----------------------------------------------



| |  |  | Energy purchase/sale transactions that take place in local markets.
| | - |  | -------------------------------------------------------------------

In order to reduce the
risk in situations of extreme drought, the Combined Group has designed a commercial policy that defines the levels of sales commitments in line with the capacity of its generating power plants in a dry year. It also includes risk mitigation terms in
certain contracts with unregulated customers and with regulated customers subject to long-term tender processes, establishing indexation polynomials that allow for reducing commodities exposure risk.

##### Table of Contents

Considering the operating conditions faced by the power generation market in Chile, with drought
and highly volatile commodity prices on international markets, the Combined Group is constantly verifying the advisability of using hedging to lessen the impacts that these price swings have on its results. As of December 31, 2015, the Combined
Group had swap hedges for 133,000 barrels of Brent oil. As of December 31, 2014, the Combined Group had swap hedges for 266,000 barrels of Brent oil for January 2015 and 350,000 MMBTU of Henry Hub gas for February 2015.

21.4 Liquidity risk

The Combined Group maintains a liquidity risk management policy that consists of entering into long-term committed banking facilities and
temporary financial investments for amounts that cover the projected needs over a period of time that is determined based on the situation and expectations for debt and capital markets.

The projected needs mentioned above include maturities of financial debt, net of financial derivatives. For further details regarding the
features and conditions of financial obligations and financial derivatives, See Notes 19 and 21, and Appendix No. 5.

As of
December 31, 2015 and 2014, the Combined Group has cash and cash equivalent totaling ThCh$144,261,845 and ThCh$132,985,927, respectively, and unconditionally available lines of long-term credit totaling ThCh$142,032,000 and ThCh$179,926,296,
respectively.

21.5 Credit risk

The Combined Group closely monitors its credit risk.

Trade receivables:

The
credit risk for receivables from the Combined Groups commercial activity has historically been very low, due to the short term period of collections from customers, resulting in non-significant cumulative receivables amounts. This situation
applies to both the electricity generating and distribution lines of business.

Financial assets:

Cash surpluses are invested in the highest-rated local and foreign financial entities (with risk rating equivalent to investment grade where
possible) with thresholds established for each entity.

Investments may be backed with treasury bonds from the countries in which the
Combined Group operates and/or with commercial papers issued by the highest rated banks; the latter are preferred, as they offer higher returns (always in line with current investment policies).

Derivative instruments are entered into with entities with solid creditworthiness; all derivative transactions are performed with entities with
investment grade ratings.

21.6 Risk measurement

The Combined Group measures the Value at Risk (VaR) of its debt positions and financial derivatives in order to monitor the risk assumed by the
Combined Group, thereby reducing volatility in the income statement.

The portfolio of positions included for the purposes of the
calculations of this value at risk include:



| |  |  | Financial debt.
| | - |  | ---------------



| |  |  | Hedging derivatives for debt.
| | - |  | -----------------------------

The VaR determined represents the potential variation in value
of the portfolio of positions described above in one quarter with a 95% confidence level. To determine the VaR, we take into account the volatility of the risk variables affecting the value of the portfolio of positions including:



| |  |  | U.S. dollar Libor interest rate.
| | - |  | --------------------------------



| |  |  | The various currencies in which our companies operate, the usual local rates banking practice.
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | The exchange rates of the various currencies used in the calculation.
| | - |  | ---------------------------------------------------------------------

---

##### Table of Contents

The calculation of VaR is based on generating possible future scenarios (at one quarter) of
market values (both spot and term) for the risk variables based on the scenarios with observable inputs for a same period (quarter) during five years.

The one-quarter 95%-confidence VaR number is calculated as the 5% percentile of the potential variations in the fair value of the portfolio in
one quarter.

Taking into account the assumptions described above, the one-quarter VaR was ThCh$95,917,431.

This amount represents the potential increase of the Debt and Derivatives Portfolio, thus these Values at Risk are inherently related,
among other factors, to the Portfolios value at each quarter end.

22.2 Derivative instruments

The risk management policy of the Combined Group uses primarily interest rate and foreign exchange rate derivatives to hedge its exposure to
interest rate and foreign currency risks.

The Combined Group classifies its derivatives as follows:



| |  |  | Cash flow hedges: Those that hedge the cash flows of the underlying hedged item.
| | - |  | --------------------------------------------------------------------------------



| |  |  | Fair value hedges: Those that hedge the fair value of the underlying hedged item.
| | - |  | ---------------------------------------------------------------------------------



| |  |  | Non-hedge derivatives: Financial derivatives that do not meet the requirements established by IFRS to be designated as hedge instruments are recorded at fair value with changes in net income (assets held for
trading).
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

22.3.1 Financial instruments whose fair value measurement is classified as Level 3.

The Company entered into certain transaction that resulted in the recognition of a financial liability measured at fair value. The Level 3 fair
value is calculated by applying a traditional discounted cash flow method. These projected cash flows include assumptions internally developed by the company that are primarily based on estimates for prices and levels of energy production and firm
capacity, as well as the costs of operating and maintaining some of our power plants.

None of the possible reasonable scenarios
foreseeable in the assumptions mentioned in the above paragraph would result in a significant change in the fair value of the financial instruments included at this level. As of December 31, 2015 and 2014, there are no financial instruments
whose fair value measurement is classified as Level 3.

i) In accordance with Official Bulletin No. 456 from the SVS (Superintendencia de Valores y Seguros de Chile), included in this
line item is the monetary correction corresponding to the accumulated paid-up capital from the date of our transition to IFRS, January 1, 2004, to December 31, 2008.

Please note that, while the Combined Group adopted the IFRS as its statutory accounting standards on January 1, 2013, the date of
transition to that international standard used was the same as that used by its parent company, Endesa, S.A. (Spain), January 1, 2004. This results from applying the exemption for that purpose in IFRS 1, First Time Adoption.

ii) Foreign currency translation differences existing at the time of transition to IFRS (IFRS 1 exemption, First Time Adoption).

|35. | INFORMATION BY SEGMENT.

35.1 Basis of segmentation
criteria

Since Enersis Chile S.A. has not yet been established as a legal entity, no chief operating decision maker existed for this
Combined Group. Consequently, the Combined Group does not yet have any operating segments as the term is defined under IFRS 8 Operating Segments. Information provided in this note includes segments as they are supposed to be analyzed by the chief
operating decision maker upon appointment of the latter.

The Combined Groups activities will be organized primarily around its core
businesses: electric energy generation and distribution. On that basis, the Combined Group has established two major business lines.

Considering that the differentiated information will be analyzed by the Combined Groups chief operating decision maker, segment
information has been organized by its core businesses.

Given that the Combined Groups corporate organization basically matches its
future business organization and, therefore, the segments, the following information is based on the financial information of the companies forming each segment. The accounting policies used to determine the segment information are the same as those
used in the preparation of the Combined Groups combined financial statements.

36.2 Indirect guarantees

As of December 31, 2015 and 2014, there are no indirect guarantees. As discussed in Note 2.1 Basis of presentation, financial debt of
Enersis stand-alone have been 100% allocated to Enersis Americas. Notwithstanding, as a result of Enersis S.A.s spin-off (for more details refer to Note 39. Subsequent Events) became effective on March 1, 2016, Enersis Chile became a
jointly liable debtor of the local bonds that were allocated to Enersis Américas, which outstanding principal as of December 31, 2015 was U.F. 0.99 million.

36.3 Lawsuits and Arbitration Proceedings.

As of the date of these combined financial statements, the most relevant contingent liabilities, for which no provision have been recognized,
involving Enersis Chile and its combined entities are as follows:

1. In 2005, three lawsuits were filed against Endesa Chile, the
Chilean Treasury and the Chilean Water Authority (DGA, in its Spanish acronym), which are currently being treated as a single proceeding, requesting that DGA Resolution No. 134, which established non-consumptive water rights in favor of Endesa
Chile to build the Neltume hydroelectric power plant project be declared null as a matter of public policy, with compensation for damages. Alternatively, the lawsuits request the compensation for damages for the losses allegedly sustained by the
plaintiffs due to the loss of their status as riparian owners along Pirihueico Lake, as well as due to the devaluation of their properties. The defendants have rejected these allegations, contending that the DGA Resolution complies with all legal
requirements, and that the exercise of this right does not cause any detriment to the plaintiffs, among other arguments. The sums involved in these suits are undetermined. This case was joined with two other cases: the first one is captioned
Arrieta v. the State and Others in the 9th Civil Court, docket 15279-2005 and the second is captioned Jordán v. the State and Others, in the 10th Civil Court, docket 1608-2005. With regard to these cases, an injunction
has been ordered against entering into any acts and contracts concerning Endesa Chiles water rights related to the Neltume project. On December 25, 2014, the Court of Law issued an unfavorable ruling against Endesa Chile that in essence
declared the right to use water established by DGA Resolution No. 134 illegal and orders its cancellation in the corresponding Water Rights Register of the correspondent Real Estate Registrar. Endesa Chile filed an appeal and cassation
resources with the Santiago Court of Appeals, which are still pending.

2. On May 24, 2011, Endesa Chile was served with a
lawsuit filed by 19 riparian owners along the Pirihueico Lake, seeking to nullify DGA Resolution No. 732, which authorized the relocation of water rights collection for the Neltume power plant, from the Pirihueico Lake drainage 900 meters
downstream along the Fuy River. The plaintiffs seek to have this annulment annotated at the margin of the notarized instrument that memorialized DGA Resolution No. 732, which approved the transfer of the collection. The plaintiffs also seek to
have the recording of the deed struck from the Water Rights Register, if entered, and to require the Chilean Treasury, the DGA and Endesa Chile to pay damages to the plaintiffs as a result of the challenged DGA Resolution. The plaintiffs seek to
reserve their right to indicate the type and amount of damages in a subsequent legal proceeding. The claim is for an undetermined amount because the plaintiffs have requested that damages be determined in another suit, once the DGA Resolution is
nullified. The discussion period has ended and the evidence action has been determined, which after notification was subject to a motion of reversal filed by the plaintiff, and to a nullity incidental plea filed by Endesa Chile, which were both
rejected. The proceeding was suspended by mutual agreement until March 9, 2013, after which it was immediately restarted. On August 20, 2013 the pending conciliation hearing took place without success. After the end of the ordinary,
extraordinary and special periods of evidence on January 22, 2015, the parties were summoned to acknowledge the ruling, and on April 23, 2015, the Court issued a ruling accepting the complaint, declaring DGA Resolution No. 732 null as
public legislation. Endesa Chile, in turn, filed a writ of appeal and reversal in the form before the Santiago Court of Appeals, which are still pending of resolution.

3. In August 2013, the Chilean Superintendency of the Environment (SMA) filed charges against Endesa Chile alleging several violations of
Exempt Resolution No. 206, dated August 2, 2007 and its supplementary and explanatory resolutions that environmentally certified the Bocamina Thermal Power Plant Extension Project. These alleged violations are related to the cooling system
discharge channel, an inoperative Bocamina I desulphurizer, non-compliance with information delivery obligations, surpassing CO limits, failures in the acoustic perimeter fence of Bocamina I, excessive noise levels and having no technological
barriers that prevent the massive entry of biomass in the intake of the central power plant. Endesa Chile submitted a compliance program that was not approved. On November 27, 2013, SMA added two additional violations to its charges. Endesa
Chile presented its defense in December 2013, partially recognizing some of these violations (which could reduce the fine by 25% in case of recognition) and contesting the remainder. On August 11, 2014, the SMA passed Resolution No. 421
that fined Endesa Chile 8,640.4 UTA for environmental non-compliances that are the subject matter of the sanction proceeding. Endesa Chile filed an illegality claim against the SMA before the Third Environmental Court of Valdivia, which on
March 27, 2015 issued a ruling that partially annulled the sanctions imposed by the SMA, instructing it to consider aggravating circumstances evidenced in connection with the calculation of the fine imposed. The company filed a writ of reversal
in substance before the Chilean Supreme Court, which was rejected, the sanction imposed was confirmed. As of December 31, 2015, the fine has been paid.

4. On May 12, 2014, Compañía Eléctrica Tarapacá S.A., (Celta) formally filed an arbitration claim against
Compañía Minera Doña Inés de Collahuasi, requesting that the Arbitration Court of Law declare that through the contracts entered into in 1995 and 2001, the parties have established a long-term contractual relation,
characterized by the economic balance that there must be in their reciprocal services supplied and that, due to the above, greater costs corresponding to the investment that must be made to comply with the emission standard contained in DS (Supreme
Decree) (MMA) No. 13, 2011 must be shared by the parties. Based on this, the defendant should start paying up to the maturity of the contract, a fixed monthly charge that through March 31, 2020 would amount to US$72,275,000 (approximately
ThCh$51,326,814) in the aggregate for the proportional part of the investments that the defendant must pay due to the Supreme Decree mentioned above.

The claim was notified on July 3, 2014. On August 8, 2014 Collahuasi contested
Celtas claim and filed a counterclaim against Celta requesting that the Court declare that Celta has violated the prohibition to call on as precedent what was agreed to in the modifications of the 2009 supply contracts, reserving the right to
discuss and prove the amount of damages. On August 26, 2014, Celta filed its response to the main claim and contested the counterclaim. On December 11, 2014, Collahuasi filed its rejoinder to the main claim and its response to the
counterclaim. On October 1, 2014, Celta filed its response to the counterclaim. Additionally, the Arbitration Judge formulated a questionnaire with questions separately to each one of the parties and also with common questions for both.

Once the parties responded to the questions, the arbitrator gave the parties a deadline of January 16, 2015, to contest or observe the
answers provided and the documents attached specifying the contrary. The arbitrator gave the parties a basis for an agreement for their review.

The management of Enersis Chile considers that the provisions recorded in the combined financial statements are adequate to cover the risks
resulting from litigation described in this Note. It does not consider there to be any additional liabilities other than those specified.

Given the characteristics of the risks covered by these provisions, it is not possible to determine a reasonable schedule of payment dates if
there are any.

36.4 Financial restrictions.

As of December 31, 2015, Enersis Chile, on a stand-alone basis, had no debt obligations and was therefore not affected by any covenants or
events of default. However, a number of the Combined Groups combined entities loan agreements, include the obligation to comply with certain financial ratios, which is normal in contracts of this nature. There are also affirmative and
negative covenants requiring the monitoring of these commitments. In addition, there are restrictions in the events-of-default clauses of the agreements which require compliance.



| | 1. | Cross Default
| | -- | -------------

Some of the financial debt contracts of Endesa Chile contain cross default
clauses. The credit line agreements governed by Chilean law, which Endesa Chile signed in February 2013, stipulate that cross default arises only in the event of non-compliance by the borrower itself, with no reference made to its subsidiaries. In
order to accelerate payment of the debt in these credit lines due to cross default originating from other debt, the amount overdue of a debt must exceed US$50 million, or the equivalent in other currencies, and other additional conditions must be
met such as the expiry of grace periods. Since being signed, these credit lines have not been disbursed. They mature in February 2016. Endesa Chiles international credit line governed by New York State law, which was signed in July 2014 and
expires in July 2019, also makes no reference to its subsidiaries, so cross default arises only in the event of non-compliance by the borrower itself. For the repayment of debt to be accelerated under this facility due to cross default on another
debt, the amount in default should exceed US$50 million or its equivalent in other currencies. It must also meet other conditions, including the expiration of any grace periods, and a formal notice of intent to accelerate the debt repayment must
have been served by creditors representing more than 50% of the amount owed or committed in the contract. This line of credit has not currently been utilized.

Regarding the bond issues of Endesa Chile registered with the United States Securities and Exchange Commission (the SEC), commonly called
Yankee bonds, a cross default can be triggered by another debt of the same company or of any of their subsidiaries, for any amount overdue provided that the principal of the debt giving rise to the cross default exceeds US$30 million or
its equivalent in other currencies. Debt acceleration due to cross default does not occur automatically but has to be demanded by the holders of at least 25% of the bonds of a certain series of Yankee bonds. The Endesa Yankee bonds mature in 2024,
2027, 2037 and 2097. For the specific Yankee Bond that was issued in April 2014 and matures in 2024, the threshold for triggering cross default increased to US$50 million or its equivalent in other currencies.

The Endesa Chile bonds issued in Chile state that cross default can be triggered only by the default of the issuer when the amount in default
exceeds US$50 million or its equivalent in other currencies. Debt acceleration requires the agreement of at least 50% of the holders of the bonds of a certain series.



| | 2. | Financial covenants
| | -- | -------------------

Financial covenants are contractual commitments with respect to minimum or
maximum financial ratios that a company is obliged to meet at certain periods of time (quarterly, annually, etc.). Most of the financial covenants of the Combined Group limit the level of indebtedness and evaluate the ability to generate cash flows
in order to service the companies debts. Various companies are also required to certify these covenants periodically. The types of covenants and their respective limits vary according to the type of debt.

##### Table of Contents

The Endesa Chile bonds issued in Chile include the following financial covenants whose
definitions and calculation formulas are established in the respective indentures based on Endesa Chiles financial statement figures:

Series H



| |  |  | Consolidated Debt Ratio: The consolidated debt ratio, which is Financial debt to Capitalization, must be no more than 0.64. Financial debt is the sum of interest-bearing loans, current; Interest-bearing loans,
non-current; Other financial liabilities, current; Other financial liabilities, non-current; and Other obligations guaranteed by the issuer or its subsidiaries; while Capitalization is the sum of Financial liabilities, Equity attributable to the
shareholders of Endesa Chile and Non-controlling interests. As of December 31, 2015, the ratio was 0.36.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Consolidated Equity: A minimum Equity of Ch$761,661 million must be maintained; this limit is adjusted at the end of each year as established in the indenture. Equity corresponds to Equity attributable to the
shareholders of Endesa Chile. As of December 31, 2015, the equity of Endesa Chile was Ch$1,474,490 million.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Financial Expense Coverage: A financial expense coverage ratio of at least 1.85 must be maintained. Financial expense coverage is the quotient between i) the gross margin plus Financial income and dividends received
from associated companies, and ii) Financial expenses; both items refer to the period of four consecutive quarters ending on the quarter being reported. For the period ended December 31, 2015, this ratio was 8.21.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Net Asset Position with Related Companies: A Net asset position must be maintained with related companies of no more than a hundred million dollars. The Net asset position with related companies is the difference
between i) the sum of Accounts receivable from related entities, current, Accounts receivable from related entities, non-current, less transactions in the ordinary course of business at less than 180 days term, short-term transactions of associates
of Endesa Chile in which Enersis Chile has no participation, and long-term transactions of associates of Endesa Chile in which Enersis Chile has no participation; and ii) the sum of Accounts payable to related entities, current; Accounts payable to
related entities, non-current, less transactions in the ordinary course of business at less than 180 days term; short-term transactions of associates of Endesa Chile in which Enersis Chile has no participation; and long-term transactions of
associates of Endesa Chile in which Enersis Chile has no participation. As of December 31, 2015, using the exchange rate prevailing on that date, the Net asset position with related companies was a negative US$341.85 million, indicating that
Enersis Chile is a net creditor of Endesa Chile rather than a net debtor.

Series M



| |  |  | Consolidated Debt Ratio: The consolidated debt ratio, which is Financial debt to Capitalization, must be no more than 0.64. Financial debt is the sum of Interest-bearing loans, current; Interest-bearing loans,
non-current; Other financial liabilities, current; and Other financial liabilities, non-current; while Capitalization is the sum of Financial liabilities, Equity attributable to the shareholders of Enersis and Non-controlling interests. As of As of
December 31, 2015, the debt ratio was 0.36.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Consolidated Equity: Same as for Series H.
| | - |  | ------------------------------------------



| |  |  | Financial Expense Coverage Ratio: Same as for Series H.
| | - |  | -------------------------------------------------------

The rest of Endesa Chiles debt
and the undisbursed credit lines include other covenants such as leverage and debt coverage ratios (debt/EBITDA ratio), while the Yankee bonds are not subject to financial covenants.

The most restrictive financial covenant for Endesa Chile as of December 31, 2015, was the Debt Ratio requirement for the credit line under
Chilean law. This credit line was closed in January 18, 2016.

Lastly, in most of the contracts, debt acceleration for non-compliance
with these covenants does not occur automatically but is subject to certain conditions, such as a cure period.

As of December 31,
2015 and 2014, none of combined entities were in default under their financial obligations summarized here or other financial obligations whose defaults might trigger the acceleration of their financial commitments.

There are no risks of cross default or other non-compliance for Enersis Chile.

36.5 Other Information

Centrales Hidroeléctricas de Aysén, S.A.

In May, 2014, the Committee of Ministers revoked the Environmental Qualification Resolution (RCA) of Hidroaysén project in which our
combined entity, Endesa Chile, participates by accepting some of the claims filed against this project. It is of public knowledge that this decision was reported before the environmental courts of Valdivia and Santiago. On January 28, 2015, it
was made public that the water rights request made by Centrales Hidroeléctricas de Aysén S.A. (hereinafter Hidroaysén) had been partially denied in 2008.

##### Table of Contents

Endesa Chile has expressed its intention to thrive at Hidroaysén the defense for water
rights and the environmental qualification granted to the project in the corresponding instances, continuing with the judicial actions already started or implementing new administrative or judicial actions that are necessary to this end, and it
maintains the belief that hydric resources of Aysén region are important for the energy development of the country.

Nevertheless,
given the current situation, there is uncertainty on the recovery of the investment made so far at Hidroaysén, since it depends both from judicial decisions and from definitions in the energy agenda which cannot be foreseen at present,
consequently the investment is not included in the portfolio of Endesa Chiles immediate projects. Consequently, at closing of Fiscal Year 2014, Endesa Chile recorded a provision for impairment of its participation in Hidroaysén S.A.
amounting to Ch$ 69,066 million (approximately US$ 121 million). See note 14.1.a).

The financial and accounting effects for Enersis
Chile of the impairment provision at Endesa Chile for its participation in Hidroaysén resulted into a charge against net results attributable to the shareholders of Enersis Chile by Ch$ 41,426 million (approximately US$ 73 million).

2. Empresa Eléctrica Pehuenche S.A.



| |  |  | On October 2, 2013, the Superintendency of Securities and Insurance (SVS) fined Empresa Eléctrica Pehuenche S.A. and its Chief Executive Officer for alleged violations of Article 54 of Law 18,046 over

Castro Márquez, a fine of 150 UF each for violation of Article 54 of Law 18,046 and Article 61 of the Regulations on Corporations in effect at the time the events penalized occurred.

The fine was applied as a result of a claim made by Tricahue Inversiones S.A. against Pehuenche based on the fact that, on April 24, 2012,
the Tricahue Chief Executive Officer went to Pehuenches offices to examine the minute books of the companys Board of Directors and stated that he was first required to sign a statement of confidentiality and indemnity in Pehuenches
favor, which he considered illegal and arbitrary.

|- | On January 8, 2016, Endesa Chile informed as a Significant Event that it resolved the illegal occupation perpetrated by three people on the first high-tension pylon which supports the 154 kV and 220 kV circuits
owned by Transelec S.A. and serve the Companys Bocamina power plant. Consequently, the Bocamina power plant resumed its operations. The financial effects due to the illegal occupation that Endesa Chile assumed during the interruption of the
transmission of electrical energy were U.S.$3.8 million decrease in the contribution margin between November 23, 2015 and January 7, 2016.

At the electrical system level, this situation increased the global costs of supplying demand, increasing spot prices and the anticipated use
of hydroelectric reserves, which in the coming months will not be available.

|- | On January 29, 2016, Endesa Chile informed as a Significant Event that on January 28, 2016, pursuant to the agreements approved at the Extraordinary Shareholders Meeting (ESM) of Endesa Chile
held on December 18, 2015, the Board of Directors of Endesa Chile was informed that the condition precedent for the spin-off of Enersis to be effective was met and, consequently, the public deed entitled Public Deed of Compliance of the
Condition of the Spin-Off of Empresa Nacional de Electricidad S.A. was issued, which established that the condition precedent has been met on January 29, 2016.
|- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Accordingly, and pursuant to what was approved at the ESM, the spin-off of Endesa Chile became effective on Tuesday, March 1, 2016, a
date as of which the new company Endesa Américas S.A. began to exist and the reduction of capital and other statutory reforms of Endesa Chile.

Additionally, as a result of formalization of Endesa Chiles spin-off, on that date the obligation was triggered for Endesa Chile to pay
taxes in Peru for a total amount of $558 million of soles (ThCh$112,187,442 approximately). This tax that will be paid during March 2016, is applicable under the Peruvian Income Tax Law to the transfer of the ownership interests that Endesa Chile

allocation of all assets that are being transferred and the final novation of the liabilities transferred pursuant to the Companys spin-off.
